7 Boring episodes out of 10 (spoilers)
What a massive waste of time.
It starts ok with the first 2 episodes. There is a mystery about why people are living inside silo, what is the door hidden at the bottom of the silo and what's going on outside. The last episode provides answers we already knew to the most obvious questions: the green nature seen outside is projected on the helmet and the hazmat suit is killing the person wearing it.
In between that, you get 7 episodes of sweet nothing about uninteresting characters doing things that barely make sense. 6 episodes are all about a stupid hard drive which supposedly contains secrets, but all we ever see when it's finally cracked is the same looping video of the fake green trees and birds which the show has shown a few times already by then. Are we supposed to be surprised or shocked? The family dramas between Juliette and father Sir Friendzone, officer Silo fever + wife and Gestapo Morpheus* + wife are all boring.
*Common can't act either.
