While I liked a lot of what they gave us in season 3, like the storylines for Fisk, for Dex, and for Nadeem, there were some things I disliked.
Namely, I feel Matt's dialogues with imaginary people were overused, and seemed more like an excuse to give Matt someone to talk to, which is more of a problem that the show created by walling him off from his loved ones. I also feel that Matt, Karen and Foggy's reconciliation in the last few episodes felt rushed. Like, as a trio, Matt, Karen and Foggy only had five or so scenes together and all of them were in the last three episodes. They needed more episodes to reconcile. I know there's a plot going on with having to bring down Fisk, but I feel like the reconciliation of the trio's relationships took a backseat to the plot.
