Hooray, I agree with him more or less 100%. It gets all the "game" stuff right, absolutely fucking NAILS voice characterization (I want to have Mark Hamill's voice-babies) and has some truly terrible one-liners. A character actually says "now the inmates are running the asylum." To describe a situation in which...prisoners have assumed control of a mental hospital. Jesus, Paul Dini.
Ah,but that character is Harley Quinn, whose entire schtick is that she thinks she's witty like the Joker, but is really just a ditz. That is defiantly something she'd say.
I don't even care if his costume has big bat eyebrows or he has an extremely stupid, hoarse, scratchy, cartoonishly deep voice; I ALWAYS take Batman seriously.
