A blind defence lawyer who takes the cases nobody pays for, and who goes out at night to reach the people the law will not.
Matt Murdock is the most Catholic character in this catalogue and the one whose guilt is most load-bearing. He is a lawyer who believes in the law and a man who goes out every night because he has decided the law is not enough, and the series he comes from never lets him settle that.
The performance is the thing that carried the character across a change of studio. He is the only person here who was introduced by one company, sat in limbo for years while nobody would say whether he counted, and came back for another one with the same actor and the same continuity intact.
