I must say, this all worries me a bit.
For one, I hope to God that we don't see him get his cut smile in the bank robbery scene. The Joker "rising to power" and "becoming Gotham's greatest villain" because of some slits on his cheeks? I hope not. I know, I know, that's jumping to a big conclusion. But...still. One scene in which to bring the Joker from a small-time crook to an evil supervillain?
Secondly, I was sort of hoping the "prologue" would be something seperate from the film. Seeing that might spoil some of it. I dunno, it probably won't.
Third..."bat sonar"? Come on. Didn't they do that same thing in BF? I'm really hoping that Batman doesn't become overly reliant on his gadgets. But between the new suit, the projectile blades, the batpod, and the "bat-sonar", I'm beginning to feel like they're shoving this whole "functional" thing down our throats.
