It was an awesome drama but the end had me asking about ten questions that I thought would have been answered by the last few minutes.
Unfortunately, I'm still as confused as I was at the beginning. It's a shame there were so many unanswered questions... that fact leads me to believe that there could be a second season. I doubt it, though. I feel that the cliff-hanger at the end was intended to be left there, all things unanswered.
I guess it was still great just had a questionable ending. How do I put it? There was no moment of catharsis. But the characters and setting and whole dystopian feel was quite cool. It reminded me of maze runner actually.
