I love all the characters in the Defenders world - and Daredevil's conflict between demanding Justice and following the Law. It's a plot that has been used many times before, but I like the dark setting of his world and the way other Marvel characters have been brought into his story.
I like this. The hero isn't superman, he's an extremely plussed up person. He's got real challenges he contends with both villainous and ethical. I like that he's a Christian, that he fights and that those things are in contest.
