We may have known Harvey Dent was going to be Two-Face but we were made to care about the character, and when he was scarred it sucked, when he died it was tragic, it all meant something even though his fate was sealed. We have no reason to care for Talia and hope she didn't turn against Bruce in this film, they have no relationship, they have no connection, she is little more than a one night stand. Was the 'twist' bad? Yes, because there wasn't something in it for everybody. Everyone who says the general audience loved it ask yourself this, did you really get anything out of it? From what I've read people are just happy Talia is in the film, why is beyond me.
Maybe, I still think the twist was fine, but the fact once the character got interesting, she was gone before she had anything else to do or develop properly was more of an issue.
