I didn't share this immediately; I wanted to take some time to absorb it, make sure I wasn't giving a kneejerk reaction. And what I've decided is...
They were close. It COULD have worked. The expression, the eyes, the teeth... Put those with something close to the Joker's classic comic book outfit--even slightly modernized/toned down--and it would have been fine. A different Joker, but one that was a viable interpretation of the character. One who could be scary.
But the tattoos make him look like he's a wanna-be psychotic comic book fan of the Joker. It looks like he's TRYING. The Joker should never, ever appear like he's TRYING to look crazy/dangerous. He just IS.
I've tried to be hopeful about the WB/DC universe. I enjoyed the BvS trailer. But... No.http://media.aintitcool.com/media/uploads/2015/harry/cdzbueiuuaatgqb_large.jpg
