I really enjoyed it when it was airing. I don't know if I'd enjoy a rewatch today, because the writing is rough in several places.
I feel its kind of similar to agents of shield where they outlived their original plan and had to adapt and come up with new plot arcs (and I think it shows, in both series). Though, I think their forced adaptions created some of the best new and interesting sci-fi concept explorations to come to TV for a while.
I'm also a sucker for "then it got worse" type shows, where the characters are struggling and doing their best to improve their situation, but every step forward is followed by being pushed a couple steps back through no fault of their own.
All that being said, I like S2 of The 100 best. S1 of the show is probably up there, starting after
