Maybe I should mention that the Riddler is a good guy these days? Batman is laughing his ass off at Edward's half arsed attempts at being a Private investigator.
Well, he's a good guy motivated by self-interest. I really do think that the current dynamic between the Riddler and the Penguin would translate well to screen. Having the movie open with them as the "good guys" and the Batman as the outlaw would be a neat twist.
