Outsiders rebooted with Dixon writing, so naturally it's good. He's really weird with how he's writing Batgirl, and I'm unsatisfied with that aspect, but it's good. The only other title Assassin is right about is Green Lantern Corps, but even that's taken a dip in quality. I'm so sick of the Kingdom Come stuff in JSA, and Green Lantern and Action Comics both blow ass.
Blue Beetle, Checkmate, Robin, Superman/Batman, Jonah Hex, and Batman (I'll defend it to the death) are the best that DC is putting out. I'd say Wonder Woman is about there, as well.
Batman Confidential just ended a very good story and the new one has promise; Tomasi's new run on Nightwing has promise, but why they insist on giving Dick absurd jobs like museum curator I will never understand, being a cop was fine; Detective Comics is decent enough, but Dini's run lost its charm a while ago; I genuinely like Supergirl at the moment, despite almost universal critical panning, but not enough to put it with the best. Gotham Underground and Salvation Run are both pretty good. Catwoman is all right, but not as good as it has been, and the new Uncle Sam mini isn't half as good as the first one.
Action Comics, Superman, Flash, JLA & JSA Classified, Superman Confidential and Brave and the Bold are all books I've dropped for reasons ranging from disappointment to sheer disgust.
