The way it should be handled is this.
Make a movie. Take the tropes that match the style and tone of the movie. But don't try to make a "comic book movie". Look at the character and try to translate it into the language of film.
It might be tautly shot crime thriller (The Dark Knight or Heat with Batman) or Indiana Jones serial action-adventure (Captain America, uh, more or less) but there's a dangerous trend of treating "superheroes" as a genre, and frankly, it became boring a long time ago. Embrace the aspects of the genre that match up to a movie rather than trying to shoehorn a script into the "comic book" category. I thought the first Iron Man was very ingrained as a cookie-cutter comic book movie, it just happened to have clever actors.
