Here's an example of a critic -- not a fan -- that didn't like TDK because it wasn't "Comic Booky":
"The centerpiece of the film is Heath Ledger’s extraordinary performance as The Joker. While I appreciated his work as an actor, the character he portrays is so thoroughly sick and twisted that I could derive no pleasure from watching him. (I’m sure the awareness of his untimely death hovered in my consciousness, as well.)
When this famous character’s antics cease to be portrayed in comic-book terms and become tangibly, frighteningly real, the playing field has clearly changed."
Uh Leonard, have you read a Batman comic book in the last, oh I don't know, 38 years? Clearly in his mind, The Joker is Cesar Romero and Jack Nicholson. The Joker in TDK IS The Joker of the comic books, totally.
It still shows me that despite some really good stuff, comic book films still have a ways to go in terms of being taken "serious."
