I saw the film, I loved it. Sure there were a few little bad points, like it felt more like a bunch of episodes strung together rather than a movie. I found myself getting ready to leave around 4 times in that movie, filled with disappointment, then my friend grabbed me and said "Wait, look, there's more!" and so I sat on down and watched with glee as Heath Ledger acted psycho for another hour or so. Now I am on the edge of my seat once more because they're bashing around the idea of yet another movie, this one focusing on The Riddler, but to be honest I would accept a piss poor excuse like "The Joker had facial re-constructive surgery" just to see the CHARACTER of The Joker again, but I know that will never happen.
May I just say; Johnny Depp for The Riddler? WTF?
