Not to sound cliched - but that Dark Knight sequel has to top the list. There were so many reasons why it should have been good. What the hell happenend?

Origin was another - just wasn't interesting unfortunately for such an important story.

Other than that I think I got my biggest dissapointments on Legends of the Dark Knight. I really enjoy the title generally, so whenever a dud story pops up, it makes me cry.

oh and the old team leaving Batgirl has broken me completely.
