Full disclosure: I'm a Batman kind of a girl. But I don't dislike Superman in the least. I haven't followed any of his titles, but have read a few great graphic novels. WHY NO GREAT MOVIE? Clearly we can love a super-powered Boy Scout—I cared naught for Cap before his movie—I can be sold.
What are the fundamental mistakes they keep making with him these days (I'm watching the latest movie, finally, and sometimes it feels so wrong the hair on my arms stands up)? Are there comic or animated storylines (including graphic novels) that could make a good movie? Especially since everyone knows his base origin story, so let's just skip that.
ETA: Another thing to skip is the "Superman is boring" line. Clearly I don't think that, so for those of us who feel he's a character with stories in him, what's the problem with getting the iconicity onto the big screen?
