[3] In a dystopian future where a community exists in a giant silo that extends 144 stories underground, 10,000 people live in a society bound by regulations they believe are meant to protect them.

The project's development was announced as a feature film at 20th Century Fox, which entered negotiations to acquire the self-published e-book Wool by Hugh Howey on May 11, 2012.

The website's critics consensus reads, "With deft writing, awe-inspiring production design and the inestimable star power of Rebecca Ferguson, Silo is a mystery box well worth opening.

[33] Richard Roeper of Chicago Sun-Times wrote that the series "holds our interest with intriguing characters and effective twists and turns", and took note of how Silo "shifts gears through a number of genres, from conspiracy thriller to big-picture social commentary to police procedural to end-times romance".

[35] Vanity Fair's Richard Lawson found the show to be a "feat of production design", adding that "Ferguson—in all her stern command—lends the series a necessary heft".

[37] Conversely, Brian Lowry of CNN believed that the "inherent mystery [...] feels stretched to the point of strained, exacerbated by characters that don't consistently pop".

The website's critics consensus reads, "Rebecca Ferguson's intrepid hero seeks answers while the rest of Silo's ensemble capably holds down the fort in this superb sophomore season.
