Lots to like but some disappointing things too. As others mentioned, not sure about the Punisher scenes here, he felt like an afterthought tacked on. Would rather they have just ended his arc an episode earlier if they wanted the focus on Matt and Elektra. Or reworked it a bit, have him take his revenge and fully become the Punisher here, but completely separate from Matt; there was really no reason to have him show up on that rooftop at all, it didn't add anything and felt very forced.
Also, I'm really not sure how I feel about Nobu killing Elektra. I can see why they went that way (distancing themselves from the film, plus also making a fair amount of sense plot wise here), but it's such an iconic moment in Daredevil history so I almost feel a bit cheated that Bullseye was removed from that. Still, I suppose Elektra isn't the only love interest on Bullseye's confirmed kill list...
