Based on the exquisite novella Wool by Hugh Howey, this is an engrossing adaptation which is bolstered by excellent writing, and polished performances, not to mention the beautiful set design which grounds the narrative. Post-apocalyptic sci-fi tends toward the relentlessly bleak, and so it is refreshing to see a world which could have become mired in despair instead provide a subtle complexity which allows for many shades of moral ambiguity in the motivations and reasoning for the Silo's machinations which is profoundly compelling, making for compulsive viewing. 8.73/10
