I could see Penguin as a wealthy, sophisticated criminal who dresses in a hat and tails. Maybe even have him carry a sort of weaponized umbrella - knife or gun charge in the end. It's back to my wanting a more grounded, cerebral villain, not the scene-chewing Joker of Dark Knight. It was fine and there were some great moments, but I grew tired of him after a while. That deeper character was what I really dug about Ra's al Ghul in Begins.
I absolutely fucking loathed Burton's take on Penguin. A mutant with - yet again - pale skin, messy hair, and red around the eyes. We get it Tim, it's your signature.
