Four words, used in the Obsidian Age arc, turned me off of Kelly's run.

"Stupid wisdom of Solomon."

I mean, I know Geoff Johns is a character hog but come on!! He could have let Kelly borrow Captain Marvel, one of the few Superman-level heroes in the DCU, just for this story, but nnnnnnoooooooooo!!! Kelly had to resort to using a revamped and renamed Apache Chief <<coughManitouRavencough>> and some newbie who looked and sounded like a refugee from Buffy the Vampire Slayer <coughFaithcough>>!

(BTW, the reason I call Johns a "character hog" is once he sticks a hero or villain in one of "his" books, they can't appear anywhere else, no matter who asks. He's the reason Giffen wound up using Mary Marvel in FKatJL, instead of Power Girl as originally planned.)
