Alright, finally finished and the final episode was really good. Overall I'd say the same about the season. Aside from the aforementioned "Karen" episode, and a little too much time spent failing to make me care about Agent Nadeem I found it well paced and entertaining, with some decent action. And Donofrio's Fisk was great as always. And while it left it open to continuation, it also ended satisfactorily enough that I won't be upset if it's the final season.
