Personally I actually thought it was fairly solid. I would have liked the season to have a more climactic ending, but I can see that they're trying to leave the doorway open for a Season 3. Jon Bernthal really stole the show to me, he was to me what Kingpin was in Season 1, just a real spotlight stealer. Definitely exuded an aura of a man who was very much at war with himself and the world. Great acting.

I was already familiar with Daredevil, the Punisher and Elektra via the comics. So going in, I wasn't as confused by this season as some others have been. I really loved Jon's take on Frank Castle. I wish there were more scenes with him, but I'd be quite happy with a Punisher series or if he shows up in other Marvel shows/movies.
I do hope there is a season 3, but they are going to be working on the Defenders after the Luke Cage and Iron Fist series. Same with Jessica Jones, not sure if they are doing a second season or not.0
