The smile on my face when I saw this week’s episode of Silo was called “Descent” could have powered every level above 125. After all, Silo excels when it digs deep into some simple, specific challenge — get from Point A to Point B despite Obstacle C; use Thing 1 to acquire Thing 2 by powering up Thing 3 — and it’s set in, y’know, a pair of massive underground Silos. I figured, well, someone’s gotta get from the top to the bottom of one of these suckers, and when it comes to that kind of action, this is a show you can trust.
