I feel the same way. For me that was Ledger's Joker. What I'm seeing so far from Leto's Joker strikes me more as attention whore than psychotic villain. Ledger's portrayal is something that I actually found disturbing. I may be proved wrong when the movie is actually released, but that's my take so far.
Though I feel differently than you do about Leto's Joker, I will agree on the attention whore bit in one regard: the tattoos. The tattoos seem sort of attention-whore-ish. Of course, they also seem somewhat realistic given how significant tattoos are in prison culture, and the fact that the Joker is likely to have some priors.
