The party scene was obligatory villain meets hero's love interest cliche, typical of the old franchise, too. (But probably necessary, I'll admit).
Two-Face's overdone injuries...how does he just refuse skin grafts? They'd sedate his ass. Would he even be given an option in his condition? And the eyelidless eyeball? Did they actually consult anyone about that?
Some of Gotham probably would hate Batman. But Gotham City is mess. Decent people shouldn't live there, they'd be happier someplace else!
