The problem is that it is just too hard to walk the line from being true to the comics without being too campy. It is easy to forgive so much when reading a comic. But when you are watching it on the screen, at times, it is hard not to stop yourself and say, "Wait, is that guy really wearing a bat-suit?". "Are people really taking him seriously?" I really liked the movie (a lot), but if Nolan and crew do anything other than what they did, they cross the line and it doesn't work. It becomes silly. You're right, the Burton films don't hold up (I hated the second one anyway). Someone put the trailers for all the movies online to compare to Nolan's and the first four movies looked ridiculous. (The third and fourth film could have really come straight from the TV show.) It's just for a character like Batman to really work on the screen, you have to have the realism.
