No, don't make the comic come to life. Unless you're adapting a single, specific comic, it's impossible to do. A character like Batman's comics are extremely varied and thematically and artistically different. Believe it or not, there ARE Batman comics as realistic - if not moreso - than Batman Begins.
What they SHOULD do, however, is bring the characters to life. It's one thing to take a certain tact when adapting a comic book. Realism (for Nolan), Gothic Noir (for Burton), it's all good in its own way. What's bad is when you start altering the very well-established status quos of the characters simply to fit whatever particular vision you have.
You like realism? That's great. Put Batman in Chicago. It's certainly looked like Chicago once or twice in the comics. Leave out some of the more fantastic elements of the universe like Clayface and the Mad Monk. What you should not do, however, is start editing every character in the film to proscribe to that realism (or whatever approach you're taking). When you start doing that - when you (seemingly) are ashamed to show the Scarecrow with his mask on, and can't even say the Joker's skin is bleached, what's the point of adaptation anymore? What's the point of translating a comic book to film when you don't even care enough about the characters to carry their integrity over into film? That's my thought.
