So it's been a couple weeks since Jack's journey came to an end. He's back in the past, and hope has been restored. But surely not everyone is happy with something that happened at one point or another during the show's airing.

I wanted to ask you all a question. Save for blatant annoyances at the end of the season (Ashi and Jack romanticism, pace of the season, how it all ended, etc.), what were you not content with, either from seasons 1-4 or season 5?
