Silo (2023) - Season 1
Score: 7 / 10
Category: Series
Platform: Apple TV+
One-line verdict
A gripping mystery with a standout lead performance, but one that ultimately feels like it values misleading the audience over a logical narrative payoff.
Why I watched this
I completed Silo on the 16th of July 2026. I chose it because it was in the top 10 list on Apple TV+, and one of my favorite actresses, Rebecca Ferguson, is the lead. I’ve always liked her work, so she was the main attraction for me. I went in totally blind—no synopsis, no spoilers—just the knowledge that it was about a silo, and that was about it.
Story & Structure
The premise is about a massive underground silo housing 10,000 residents across 144 levels. It’s divided into distinct sections: Mechanical at the bottom, Judicial in the midsection, and IT at the top. The entire society is governed by "The Pact," a strict set of rules designed to maintain order and prevent people from wanting to leave. Outside the silo is a toxic, barren wasteland—or at least, that’s what the giant screen in the cafeteria shows everyone.The mystery starts when the local sheriff asks to leave, and Juliette (Ferguson), a mechanical engineer, is thrust into the role of sheriff to investigate the suspicious death of her lover. The show is a slow burn, meticulously explaining the rules and the history of this world, which supposedly dates back 140 years with no records of what came before.
What worked
What worked for me is, of course, the mystery. The central question—what is actually outside?—is incredibly engaging. The design of the silo itself is excellent; it’s a grey, dark, claustrophobic world that perfectly reflects a society that hasn't seen the sun in over a century.Rebecca Ferguson is brilliant. She brings an intensity to Juliette that makes her drive to find the truth completely believable. But for me, Tim Robbins as Bernard was the standout. He plays the head of IT and acting mayor with such nuance that you start to believe his actions are a necessity rather than pure villainy. Common as Robert Sims was also a very believable, brutal antagonist. The suspense builds well, and every episode gives you just enough information to keep you hooked.
What didn’t
This is where I have a major disagreement with the writing. Throughout the season, the show works very hard to mislead the viewer, but it does so in a way that feels logically inconsistent.In Episode 3, when Juliette is repairing the generator and they shut down the power, there is a quick flicker—maybe 2 seconds—where the cafeteria screen shows a beautiful, lush green landscape. This led me to believe that the "barren" view was the lie. However, the finale reveals that the green view is actually the fake AR overlay being fed to the people sent outside to clean, and the world really is barren.This makes no sense to me. If the intention of the silo management is to keep people inside, why would they provide a beautiful "cheat" view to the person stepping out to clean? It defeats the purpose. Those who want to go outside already suspect it’s better looking. If they go out and realize it’s actually a wasteland, they’d know they made a mistake. Why bother giving them a fake good view to "cheat" them into cleaning? It feels like the writers changed the story at the end just to flip the script on the audience. That flicker during the power outage was meant to mislead us, the viewers, but in the context of the show’s world, it doesn't serve a logical purpose for the residents.I also found some of Juliette's actions as sheriff a bit unbelievable. She’s a mechanical engineer, yet she’s suddenly breaking into houses and conducting high-level investigations like a seasoned detective. It didn't quite feel earned for her character.
What others think
Critics have generally loved Silo, praising it as one of the best sci-fi shows on television. Rebecca Ferguson’s performance and the world-building are almost universally acclaimed. However, the "AR overlay" reveal in the finale has been a massive point of debate. While many fans love the twist—realizing that the "truth" they were chasing was actually the lie—there are plenty of viewers who share my frustration. The consensus is that the show is a masterclass in tension, but your enjoyment of the ending depends entirely on whether you accept the logic of the "cleaner's" perspective.
Final thoughts
As a final verdict, I’m giving Silo a 7 out of 10. I wanted to give it an 8, but the way it misled me from the beginning felt a bit cheap. The ending didn't satisfy my curiosity; it felt like the story was just changed at the end by the writer to force a cliffhanger for Season 2. I would still recommend it because it reflects a lot about the world we live in—the "what-is-not-what-it-seems" part is very relevant. But for me, the direction went off track at the finish line.
