I wasn't a fan of Leto's Joker, but it wasn't his performance - I thought it was okay. (Wasn't a fan of his choices for the head tattoo and grill though) Maybe the cut footage had better stuff. The main reason I didn't like his Joker was how he was written and conceived. They really highlighted the gangster aspect of him, rather than the madman. He just came across as a whacky criminal more than a larger than life psychopath who could challenge Batman.
