Besides clown make up and a fun slide down a pile of money... he was not the Joker. That performance was pretty brilliant (I ain't sayin' Oscar worthy... but brilliant), but it wasn't the Joker to me. No jokes, no tricks, no treats.... dude was just a psychopath. Does it work in the Nolanverse? Absolutely. But as a comic fan... that ain't the Clown Prince of Crime.

He was as much the Joker as Danny DeVito was the Penguin.
