I feel like they need to kick things up a few notches when it comes to the classic Joker look and delivery. More purple, more laughing (not just the old man laugh or purring), a bit more "clown" and less fashion freak. I understand the need to try something different, but when you combine all of the experiments, it's too much. The tattoos, the club, the grillz, no permanent smile, the chains, barely any purple, and so far he's more obsessed with Harley than Batman.
I like his performance in some scenes for sure but even when he's doing fine, not making a fool of himself, it's brought down by the design. And i blame Leto too because he was really into it.
There's not going to be recast. They're not going to drop the tattoo's and the grillz because THEY are happy with it and for the sake of continuity. But they can change some things here and there.
As for the concept art, i can't believe how HIDEOUS it is. It's the worst.
