I loved this show. I'm going to watch it for a 2nd time. Intriguing and keeps you on the edge of your seat.
The last few episodes seemed forced, almost like the writers were just trying to fill space. Watching the documentaries, the creator says he felt it should have been completed after 7 episodes & they had to stretch it 10 more. After all that, I read they had to abruptly conclude the series and the ending did seem off.
Besides all that, the series is really great. The concept is different, like a sort of sci fi horror miniseries.
