To sum up the primary problem in this last season of Jessica Jones, is that Trish Walker is the worst. Her character nearly single handily brought this show to its knees. The main villain is also really dry this season. Compared to Killgrave, this sideshow boring dummy doesn't even compare.
Trish is insanely annoying, obnoxious, buts in when she's not invited, and the show focuses way too many large segments of episodes on her. The writing for her character is bizarre and one of the worst storylines and arcs I've ever seen. I literally was yelling at the screen because of how annoying she is. In this season her idiotic antics were even worse than the previous season.
As a whole, I'm sad to see the character Jessica Jones go, but the show really did need an end to itself. Hopefully we'll see Jessica return again, with Daredevil, Luke Cage, and The Punisher.
PS: Please stay gone Iron Fist ;)
