Re: How close should a comic book movie be to its source material?
Close enough that the characters in the film are still recognizable as those on the page. However, religiously adapting the material can get boring and sometimes even alienate those who aren't fans by being too outlandish or something to that extent. You're really adapting the characters, not just the stories. There isn't enough room for 50+ years of history in even the longest-running trilogy or film series or whatever.
If any character has ever earned the right to enjoy a happy retirement, it is Bruce Wayne. Nolan ought to be commended for caring enough about the character and believing enough in his own vision to provide a definitive, satisfying ending to the story of an ordinary man who turned tragedy into the motivation to accomplish something extraordinary.
