Haven't read a lot yet, but I really liked Batman Inc, and Flash was terrific. Also I enjoyed the Nighthawk & Cinnamon finale in All-Star Western, but I haven't read the Jonah Hex story yet.
But the comic I'm most looking forward to this week is Resident Alien #1 from Dark Horse, by Steve Parkhouse and Peter Hogan. The three installments from Dark Horse Presents (collected in issue 0) were among my favorite stories that book has published so far, and I've been waiting eagerly for this issue for 4 or 5 months, it seems. It's about an alien living incognito in a small northwestern town who winds up becoming the town's doctor when the old one is murdered -- it's almost like Northern Exposure with a sci-fi twist. Give it a look -- I don't think you'll regret it!
