Show started off really well, was tense and interesting seeing how society reinvents itself. First couple of seasons where great.
Then it's like the writers ran out of new ideas so they kept recycling old ones and dragging out episodes just to meet runtimes.
It got so bad I stopped watching after season 9. When I heard season 11 would be the last I decided to finish the series, every episode of season 10 is a chore, secondary characters are getting entire episodes, weird flashbacks that don't add anything.
