Having recently read "Joe Chill in Hell" in the Batman: The Black Glove hardcover, I would say I'm not too hot about seeing the original characterizations coming back. For characters like Batman, where their first portrayal was an about face in comparison to what we know now, they can stay as they are. I like Morrison's run on Batman, but one of the things I disagree with the most is the aforementioned story. I don't see how a character that once helped a criminal commit suicide out of guilt can be such a hypocrite about guns later on. Some of the ideas are interesting, true, but as examples of things that don't mesh with the real reasons why these characters are beloved. It's best to respect the history for what it is and move on from there.
