TL;DR – The tension ramps up as the power shuts down.

Silo Review –
I think that as a society, we take the connection to water and electricity for granted and would have no concept of what to do if it went out for an hour, let alone more. But what happens when you live deep underground and that power generator is the only thing keeping you from living in the dark, allowing you to breathe … well suddenly, you need to care about it much more.
So to set the scene, we discovered two very interesting things at the end of Holston’s Pick. First, Holston (David Oyelowo) picked Juliette Nichols (Rebecca Ferguson) to be his replacement as sheriff. Also that Juliette’s late partner found a hidden door in the deep caverns where they hid the machine that dug the Silo. As the mystery abounds, Mayor Ruth Jahns (Geraldine James) and Deputy Marnes (Will Patton) make the slow trip down 140 levels to the bowels of the Silo, where it is not just the generator that is shaking things apart.Now from here, we will be looking at the episode as a whole, so there will be some [SPOILERS] ahead.
