Enjoyed the movie a lot but certainly felt some characters were different from their portrayal in the comics book (not necessarily a bad thing).
My question: Which of the major characters in the film was least like his/her counterpart in the comic books?
For arguments sake, lets say we're looking for lack of similarity between the two during any part of the character's comic book history. So that if the movie portrayal resembles an earlier version of the comic book character, that counts as similar.
If you vote please try to leave a rationale. Also it would be interesting to know whether you think the changes were necessary and/or beneficial for the movie.
