I'll have to wait to write a review of the first issue of Infinite Crisis, but here are a few to tide you over.
Villains United 6: This Crisis mini was probably my favorite of the bunch, thanks mostly to Gail Simone's writing and a quirky cast of characters. The art was nice, too. The twist with the two Luthers, Catman's warning to Ollie at the end, all nice touches.
Hawkman 45: Nice ending to this story arc. Carter's "death" and resurrection had a plausible explaination and the cameos at the end of his friends and fellow heroes kept things in continuity. Golden Eagle's origin and true nature and motives were handled well and not at all what I'd expected. I had been worried about this story arc from the moment of Carter's death, so was pleased by how this turned out.
Green Arrow 55: Lots of action, but still, mostly setup for what's to come — Dr. Light's vengeance against Ollie. I can't wait. Oh, and the art was nice, too. I still miss Hester and Park, but the art we currently have is much better than what we got when they left the book.
