On the subject of Hamill Joker, he was perfect in nearly every way, except one. He seemed to be too hung up on money sometimes. One specific episode comes to mind, where a dead mobster left Joker millions in his will. Joker was so blinded by the sudden influx of cash, he didn't realize it was mostly counterfeit. Granted, Joker was dead broke at the beginning of the episode, but I never imagined Joker to need very much money or resources to wreak havoc.
Hopefully Letos Joker can take a queue from Ledger's Joker in regrets to money. Showing people he enjoys what he buys with it, but he doesn't worship it like typical criminals.
