Superman fans please do not attack me! :) You know what's my problem with Superman? I really like what I read in this article, but I don't think I've read any good Superman story focusing of these character traits. I've read AC 775 and All-star and I found them to be just OK. The only Superman story I really like is "Superman and the Legion of Super-Heroes" by Johns. Any suggestion of Superman stories that focus on him morality are more than welcome.
PS: My dream is a 8-12 part Superman story by Gaiman. I believe He's capable of showing the depth of Superman, beyond his powers.
