“The Secrets of the Underground Silo” (2023) Review: Power that suppresses questions is more frightening than the outside

LUX · November 9, 2026

If someone claims to be offering protection but also prevents you from asking questions, can you truly trust that protection? My answer is no. One does not have the right to silence someone else simply because they are aware of a risk. The fear in “The Secret of the Underground Silo” is not only found on the outside; it also resides in those who decide what questions can be asked from within.

A silo is a massive underground residential structure where people live in isolation from the outside world. Residents are taught that the outside world is dangerous, but they do not know who built the silo. They cannot freely access records or objects that reveal the past. There are many rules governing their lives, but they have no freedom to question or examine those rules.

The drama initially focuses on Sheriff Holston and his wife, Allison. Allison questions the procedures for childbirth and official explanations, and these questions disrupt the couple’s lives. Her desire to go outside leads to an irreversible exile. This is not a place where one can afford to be careless with their words. They have even eliminated the “cancel” button.

I felt more tension when someone became endangered simply for asking a question, than I did waiting for the answer to a secret. This is the point where the order that must be maintained and the person who must be protected diverge. I believe that *Silo* is most effective not when it hides the answer to a secret, but when it makes one question the power that uses safety as an excuse to suppress questions.

Does saying “we will save you” justify blocking questions?

It is unacceptable to prevent questions simply in the name of safety. What this drama did well in its early episodes was to show that prohibition through the couple’s lives. Before explaining the rules, it made the audience feel what is lost because of those rules.

Holston is a sheriff who maintains order. Such a man’s wife begins to doubt the community’s explanation. I consider this relationship important.

This is not the rebellion of someone who has hated the system from the beginning. Even for a couple who lived within a certain order, there are questions that are simply unbearable. Therefore, it is difficult to dismiss Allison’s questions as merely the commotion of a dangerous person.

The concept of managing childbirth also exerts a similar influence. The phrase “survival of the community” directly enters the lives of people who want to have children. Grand justifications are used to permit and prohibit the most personal desires.

The claim that childbirth must be managed and the right to reject an explanation are separate matters. However, in this situation, both are presented simultaneously. The resident must accept the decision, and the party making the decision must avoid appearing suspicious.

When Allison questions an official explanation, the important thing is not whether she got the answer right or wrong. The important thing is whether she has a place to examine the decisions that have been made about her life. Silo does not provide that place.

The rule that once spoken, a statement cannot be retracted, is therefore cruel. Even if the person who made the statement changes their mind, the system does not stop. While the rule is intended to help people survive, it does not provide an opportunity for reconsideration.

I was more afraid of the system that accepted and processed those choices than of the choices themselves. People become fearful and confused, and they change their words. This place has no room for people like that.

The plot, which initially focuses on Holston and Allison, is also well-constructed. If the story had only presented a massive secret from the beginning, I would have immediately tried to deduce the building’s true nature. However, by placing the couple in the forefront, it creates a reason to demand an explanation even before one is provided.

The order that the sheriff had maintained ultimately failed to protect his own life. This discrepancy is what separates the subsequent investigation from mere curiosity. The question of who concealed what is now a matter concerning the living.

The couple’s departure leaves a vacancy, which Juliet fills. Juliet is a technician skilled in repairing generators. However, just because there are reasons to be suspicious does not mean that all suspicions are evidence. So, what will Juliet use to prove her judgment?

Juliet doesn’t begin with suspicion; she looks for the cause of the problem

The repair of the generator proves that Juliet’s suspicion was not a vague form of rebellion. She is someone who verifies the cause herself before rejecting someone else’s explanation.

The generator is a vital piece of equipment that supports the life of this underground community. Juliet is a technician who maintains this equipment, and she performs her duties in a dangerous environment. It is advisable to conclude the job description without using a quote.

I held my breath watching the repair. What was more concerning than the fact that the machine had broken down was the fact that a person was risking their safety to fix it. The safety of the residents cannot be maintained by rules alone.

Someone has to actually go to the place that is broken. Juliet is the one who does that. So, even when he later questions the community’s explanations, his attitude doesn’t feel like sudden bravery.

Can the demand to trust explanations rather than seek the cause be effective when dealing with people, just as it might be with machines? This demand does not work with Juliet. She is someone who knows that the words “it is fixed” and the actual state of the machine working are different.

This habit continues even when investigating the death of his former lover, George. He accepts the position of sheriff because he wants to know the truth about George’s death, but the title does not change his way of thinking. He does not stop at explanations that do not make sense.

Sheriff, are you going to take the case apart like a generator?

This joke is quite an accurate description of a person. The person who was looking for the cause of the problem is now looking for loopholes in the official explanation. The effort to repair the generator and the act of investigating the death both stem from the same stubbornness.

Of course, the desperation of someone who has lost a loved one is not necessarily proof of anything. I appreciate that the drama maintains this distinction. Juliet’s sadness is the reason she began her investigation. I believe in her investigation for a separate reason: she seeks evidence independently, without relying on the explanations of others.

Here, the significance of the generator scene becomes clear. Juliet is someone who understands, through her own experience, what is necessary for the community to survive. This is not a story where someone who doesn’t understand the need for safety criticizes the excuse of “safety.”

He also understands that covering up a malfunction is not a solution. Therefore, the act of demanding an explanation is different from an impulse to disrupt order. It is someone who is trying to verify whether something is working correctly who is asking difficult questions.

The problem is that, unlike machines, the power structure here does not allow itself to be examined. The more Juliet tries to find evidence, the more those who control the information obstruct her path. The conflict between the two main characters derives its strength from this.

Ferguson’s stubbornness clashes with Robbins’ composure

The main characters demonstrate the difference between those who ask questions and those who prevent questions from being asked. However, the supporting characters do not reach the same level of depth.

Rebecca Ferguson, who plays Juliet, embodies stubbornness not just in her words but also in her actions. Her body movements, such as leaning towards the danger when repairing the generator, convey the technician’s confidence. This same attitude of not easily accepting others’ explanations carries over into the investigation, demonstrating her focus.

I like that this portrayal doesn’t automatically make Juliet a perfect person. She is someone who endures an uncomfortable situation until she understands it, rather than easily trusting and becoming comfortable with someone. Because of her harsh attitude, the questions she asks feel like a difficult task, rather than a grand declaration.

Tim Robbins, playing the role of Bernard, who leads the technology department, uses composure as his weapon. Even when confronting Juliet, he maintains the calm demeanor of an administrator. This composure is overlaid with the threat of someone who controls information.

Not being angry does not mean that a person is ready to engage in a conversation. Robin clearly highlights this distinction. The attitude of listening to the other person’s questions is entirely different from the attitude of determining the scope of the response to be given.

When you see the two of them together, the unfairness of power becomes clear. Juliet has to move to question even a single explanation. Bernard remains calm simply because he holds the explanation.

One side focuses on verifying information, while the other manages the process of verification. Therefore, I do not view this conflict solely as a matter of personality differences. The two actors demonstrate different approaches in terms of who can access the evidence.

Billings, played by Chinaza Uche, is a deputy sheriff who values regulations. When he tries to conceal his trembling hands, it reveals that even those who enforce the rules are also afraid of those rules.

Common, who plays the role of Simms, the one responsible for exerting pressure from the judiciary, is imposing, but his limited range of emotions in the scenes of pursuit and confrontation fails to reveal the inner thoughts of someone who follows power.

This difference is not insignificant. Billing’s anxiety expands the scope of who might be harmed. In contrast, Simms’ repeated pressure only serves to reaffirm already known threats.

I am not disappointed that Simms is less frightening. What I wanted to understand more was why Simms adheres to that order. When someone who prevents questions also has their own reasons, the persistence of that order becomes even more frightening.

While a slow pace may not fully reveal the inner workings of the characters, what does it offer in return, compensating for the wait?

The problem isn’t the slowness, but whether the people become deeper as we wait

I partially agree with the criticism that the answers are being delayed excessively. However, I would not consider all the time spent adhering to rules that restrict daily life as unnecessary.

There are people who obtain permission to give birth, conceal old records, and carefully observe their surroundings before asking questions. These situations do not immediately reveal the identity of those outside. Instead, they make it understandable why the residents find it difficult to demand explanations.

The grand staircase and living areas are not merely decorative; they are integral to the structure. Residents live in the same building but work and move in different areas. There is a significant gap between the idea of knowing the entire community and the reality of simply getting through the day within one’s own designated space.

I appreciate the slow pace that reveals the distance. It’s more accurate than lines of dialogue about the fear of power; it’s the process of a single record becoming dangerous that is truly revealing. It shows how a system that promises security also ends up controlling curiosity.

However, if the investigation progresses slowly and the person remains in their position, the situation changes. Sims putting pressure on him again does not make us understand any better why people follow him. The time spent repeatedly making threats is different from the time spent getting to know the person involved.

It is acceptable to wait, but it would be problematic if only the ticket numbers increase while the content of the consultations remains the same.

Billing is more regrettable. He is someone who must conceal his own trembling while enforcing the rules. This anxiety is a good starting point for him to re-examine the rules he upholds.

However, the drama does not go far enough from its starting point. While the difference between Billings and Juliet is clear, I wanted to explore his feelings of clinging to the rules for a longer period. There was room to delve deeper into the fact that even the enforcer is uneasy within a system that suppresses questions.

The decision to expand the first half of the original work, “Wool,” and increase the roles of the judiciary and Billings was the right direction. This is because it provides more opportunities to show how power typically operates when it tries to conceal secrets. However, if this expanded space is filled only with pressure and pursuit, the benefits of the expansion will be diminished.

What I am requesting is not a service that provides one correct answer per episode. Rather, I want to see more clearly who remains silent and who adheres to the rules while the answer is delayed. This allows the waiting time to become a period for understanding this community.

So, instead of providing all the answers at the end, what should be achieved?

The fact that power is wrong does not constitute proof of my hopes

The final point clearly distinguishes between questioning official explanations and believing the answers one wants to hear. I believe that this distinction is why the season maintained the questions it raised at the beginning until the very end.

The mere fact that power concealed information does not automatically make the opposing argument true. If hidden records are discovered, the explanation must be re-examined. However, this does not mean that one can fill in the gaps with a narrative of one’s own choosing.

This drama excels at avoiding easy satisfaction at the end. It doesn’t demand that viewers accept Juliet’s expectations as fact simply because they have taken her side. It maintains a distance between feelings of support and the judgment of evidence.

“Juliet, the fact that I don’t believe what my superior says doesn’t mean my wish is evidence.”

This statement is more important to me than it is to Juliet, because I am the one who is following him. When you begin to doubt the person in control, you may want to readily believe the stories he has denied. However, if only the person who is explaining things changes, but the habit of verifying information remains the same, then nothing has really changed.

Therefore, I highly value the choice where the working materials play a crucial role. I will leave how they are used unspecified. The important thing is that Juliet’s technical knowledge and the help of her colleagues are essential throughout the entire process.

The experience gained by someone who repaired generators does not disappear simply because they become a sheriff. The ability to understand the properties of materials and to determine whether they can be used effectively becomes valuable again. The work shown earlier remains a basis for judgment.

The colleagues’ help does not transform a judgment into a solo victory. Juliet is not entitled to ask questions simply because she is a genius who understands everything. Colleagues open the way for Juliet to make judgments and take actions, using their own skills. Protecting the right to ask questions also requires mutual assistance.

This approach goes beyond simply challenging explanations of power; it provides a concrete method for doing so. Instead of relying on unsubstantiated claims, it emphasizes examining tangible conditions. It asks not only “what” to believe, but also “on what basis” to believe it.

The power of the silo dictates that the residents must accept the explanations provided. The Juliet at the end does not stop at replacing those explanations with another belief. The struggle to reclaim the right to verification remains at the heart of the story.

My criteria for evaluating this are not whether all the secrets have been revealed, but whether this action can be justified. Now, the question is whether this drama is worth the time spent either waiting for the correct answers or gaining the ability to ask questions.

Overall assessment: There is no reason to remain silent just because it claims to help us survive

My rating is 4 out of 5 stars. Despite the slow pacing, it is worth watching until the end of the 10th episode. This drama is excellent because it makes you question the power that prevents questions, even when it uses safety as an excuse, rather than revealing the answer to a secret. It does not take away the right to demand an explanation, even if it claims to be saving lives.

The scene involving Juliet’s labor, the conflict between Ferguson and Robins, and the final judgment are all connected by the same underlying question. While this connection is commendable, the film’s overall score is lowered due to its slow pacing and the supporting characters, who are not developed sufficiently.

If you enjoy stories that explore the rules of life in enclosed spaces and the control of information, I recommend this one. It’s interesting to see who reads the records and who is allowed to explain them to others. The story focuses on how a massive secret can overshadow even the most ordinary days.

On the other hand, if you expect a major answer every time, you might find it frustrating. It is also not suitable for those who expect all the secrets of the world to be revealed within a single season. Questions are good, but there is no obligation to enjoy waiting for answers.

When examining the case, it is important not to focus solely on what lies outside. Even when faced with the same questions, some individuals gain access to records, while others are subjected to suspicion. By understanding this difference, one can begin to comprehend the reasons behind the slow pace of the investigation.

Observe whether Juliet continues to exhibit the habits she had when she was a technician, even after becoming a sheriff. Juliet trusts the results she obtains through hands-on examination and testing, rather than relying on confident explanations. I believe that this technician’s stubbornness is what keeps this story going. The ending becomes even clearer when viewed through this lens.

The next work to be examined is “Fallout.” While “Silo” questions explanations from within, “Fallout” ventures to the ground surface to test the established order. It provides a good comparison of how people change when the information controlled by the protectors is revealed.

I found the way this drama suppressed questions from within, rather than what it concealed about the outside world, to be more frightening.

★★★★☆ (4/5) — The power that suppresses questions is more frightening than the dangers outside.
