An incredibly stupid arc of Jeph Loeb's Superman/Batman (but then, really, pretty much all of S/B could be described that way).What's Public Enemies?
I would prefer they went in a different direction than anything adapted from Superman/Batman. Considering the potential it has, this book never fails to disappoint. I wouldn't mind seeing something done with the Green Lantern Corp.
The first two arcs were worthy stories... I'd like to see the second arc, with Darkseid and the re-introduction of Supergirl. But mostly I just want to see that because I never get tired of watching Superman and Darkseid go at it. Plus, the possibility of hearing Michael Ironside voice Darkseid again.
