Silo.
It was promising but turned out rather generic and, somehow, mediocre.
The premise is really interesting, curious and engaging that goes beyond the overused tropes coming with "people in a bunker", "people ending in some place they don't know", etc... kind of à-la Lost and such.
There was a great opportunity to work on world building, but it turned out to be a, yet another, show centered around a character that evolves through the episodes. The show goes from being about the "Silo" to "whatever the name of the character is".
It feels a bit pointless.
