My big problem with the Daredevil TV series is that I was watching it for a Marvel Super Hero fix, and at the end of the day Daredevil just didn't come across as being all that super heroic to me. He wound up getting hurt and beat up way too much and having too much trouble taking out regular guys. Now granted it's pretty unreal he could win some of those fights at all, but we're dealing with a super hero and I expect him to be able to take out some Russian gangsters without a scratch because he's a super hero. I think "Arrow" did a better job of doing the whole street level thing to be honest, and I see that as the big competition for this show.
Daredevil wasn't bad, and it has potential, but it was too much of an extended origin, and to be honest I'm not sure if I can see how they will justify a radical increase of his abilities to more comic book like levels.
Daredevil actually raised some concerns for me about how they are going to handle the other series they plan as part of this project. I seem to remember they have other shows planned and then want to tie them all together into "The Defenders" (which is kind of funny since it seems more like the "Heroes For Hire" roster from what I remember). Apparently Jessica Jones, Luke Cage, and Iron Fist are all going to get their own shows. The big thing is that with the trouble they have making Daredevil seem properly superheroic I can't imagine what it's going to be like when they bring someone like Cage out who actually has super powers (and half his thing is he's almost impossible to hurt, especially with regular stuff) assuming they can find a way to do that well, how are they going to justify Daredevil hanging around with that crowd. Usually when they bring the more or less super-normal into a group of guys with powers "supernormal" is a lot more effective against the stuff we've seen Daredevil run into so far. See, for me when they did Daredevil it should have been a big deal when he ran into a Ninja and had problems, meeting someone with the same levels of skills, but really it didn't impress me so much to have him getting pounded that way since it seemed like everyone else was taking a piece out of him before he won as well, so you know... he never sold me as being unbelievably good, compared to a character where I'd think it should be impressive to even be able to lay a hand on the guy if he doesn't want you to.
