Just finished, that was a lot of fun and had a few twists I liked.
I liked how the Blacksmith was revealed, I didn't see it coming and it ties into why Frank Castles does what he does.
Talking about him, the Punisher absolute stole the season, damn, I'll go as far as to say he carries it because every time he gets on the screen shit gets real. He doesn't talk a lot, but when he does is because he is about to drop some knowledge.
I really liked the use of Page and Foggy here. I complain I always have with superhero series is that they make their support characters either useless or bait, and here, even if Page was kidnapped/on trouble a lot, it worked for furthering the story and still made her feel important. Foggy was a boss in the law heavy episodes, covering for Matt when he was too busy.
Electra was the weak link for me this season, I don't know why but her character is too volatile for my taste, I get that is kind of the point but by the end her story arc feels rushed. I hope when she comes back she is not just full mindless zombie because that would be predictable and lame. Also, WTF Stick, you know they have a way to get immortality, why not just burn her body or something? Is this your game Stick? Is this part of your plan? And Matt can't be this dumb either, he has seen the same guy raise like nothing like 3 times, at least cut her head or something, jeeez.
So Punisher is going to get its own series, right? Right?
Edit: Oh and to add to the finale, by then Daredevil was in full "I don't give a fuck" mode and was ok with Electra and Punisher killing the jobbers, so I think he believes he killed Nobu. Or at least expected Stick to kill it for him. His original plan was to have him rot on hell and he had him restrained, so he totally was going for the kill there.
