I've watched the first 4 out of 13 today.
On the one hand, it's really well made, writing is compelling, and it looks shockingly great. Casting seems to have done a rock solid job all around.
On the other hand, it's incredibly dour and mires in misery, it doesn't feel like it belongs in the Marvel Cinematic Universe at all, and it doesn't quite feel like Daredevil the character (except as Frank Miller saw it post-TDKR).
So I'm torn, this isn't Daredevil yet, this isn't truly the man without fear, and it's barely Marvel at all. It may be The Man Without Fear, but that's not the same thing.
So is this Netflix and Marvel's answer to Nolan's "The Dark Knight" where there was a compelling story and also Batman was there sometimes? Maybe, but at least here our dark knight hero vigilante actually has character developing.
