This film is really starting to seem a lot like Batman Returns - it appears to be a lot darker (perhaps more than some people can handle) what with the hanging fake Batmen, a bomb in some guy's stomach, The Joker going berserk with a machine gun on open street, Batman's "bad cop" interrogation scene, both the Mayor and Loeb biting the bullet...sure, it may sound great for us comic book fans but the general audience might find it a little too much for a PG-13 movie.
Another thing that makes TDK resemble Batman Returns is the amount of changes the film makes to the Batman mythos.
But then again, I loved Batman Returns. Save for the campy and self-parody moments, it had a great story and was a really well-written and acted film. I'm just slightly worried about the reactions of the average moviegoer or more specifically speaking, younger audiences and how it will affect TDK's box office. Otherwise, I am expecting nothing short of yet another amazing film from the Nolan brothers even if it is significantly different from what we expected.
