Have to agree with polonyc2 here. Heath Ledger's joker set the bar pretty high and many look at his joker as the one to emulate. But, Jared Leto is a fantastic actor and I like that they haven't tried to carbon copy Heath.
I am certain Jared Leto's ultra maniacal, bat shit crazy joker in SS will become a fan favourite once they get past their Heath grief.
Try again.....he's not playing the joker. I could give two shitsabout Ledger's joker.......Mark Hamill is the only true joker.
I disklike this joker because like someone says above he looks like some loser punk rocker.....which isn't the character.
