Personally, I'd like to see more comic book movies done like James Bond films in one area.
James Bond films, for all their flaws, don't feel the need to re-establish the hero's origin or what he's been up to between films every time they make one.
Instead, the producers realize that the audience knows that James Bond is a secret agent with cool gimmicks and gets right into the action. They also realize that the audience can accept that the series is decades old and don't feel the need to explain why the hero doesn't age (or why he is a different actor every seven or so years).
Why can't a Superman movie proceed from the same basic assumption, that everyone knows Superman is an alien from Kypton who disguises himself as Clark Kent, etc, instead of wasting half or more of a movie recapping an origin everyone in America already knows.
