I liked most of it, and I think it works well as a follow up to the first season: Karen and Foggy in particular get fleshed out more in interesting ways.
I actually felt a bit let down with the way they handled Stick and the Chaste. In the comics, Stick is scary good, and it is that ability that makes him a reasonable instructor for Daredevil and Elektra. The Netflix Stick is, at least as far as I've seen, probably only as good as Daredevil at the moment. That seems to be a weird "imbalance" particularly given Stick's insufferable arrogance, which is true to his original character. And as for the Chaste, there's a moment in the series where Stick essentially says "time to bring in the professionals." I got absolutely giddy at that point. And then ...
I'm still processing how I feel about this incarnation of Elektra. I'm not the instant convert many others are. I think for me the problem was that they appeared to have more time to develop Matt's relationship with Elektra but didn't use it efficiently: it felt rushed. And that made the big payoff feel like it landed less strongly than it could have. I think it is definitely a good Elektra, but whether it is a great Elektra for me might have to wait until Season three.
If there is a weak spot in Daredevil, it is ironically Daredevil himself. Matt isn't explored as deeply in season two as in season one. It is as if season one was about exploring what makes Matt tick, and season two is about how the people in orbit around Matt are affected by him, his struggles, and his secrets.
Overall, though, as with season one I think it is some of the best television I've seen recently. I think the dynamic range of Marvel's productions is a really good one, from the light hearted Guardians of the Galaxy on one end, to Daredevil and Jessica Jones on the other. I think Warner needs to learn that dark is a metaphor, not a palette, something I think the Netflix series seems to get.
Definitely looking forward to Luke Cage.
