Batman: Earth One is a reboot of the Batman story written by Geoff Johns and illustrated by Gary Frank. It's a timely book, coinciding with the conclusion of the trilogy of Christopher Nolan Batman films, and it offers a very good entry to the series for people who haven't followed it closely until now.
We've seen a lot of remixes and retellings of the Batman origin story, and I think this is my favorite to date. Johns dispenses with some of the less plausible aspects of the Batman myth, and presents us with a Gotham that is out of control, corrupt, dark and glorious. There's a haunted house, there are serial killers, Hollywood phonies, and a mayor named Oswald Cobblepot.
The book moves swiftly, hits all the right emotional notes, and is beautifully made and illustrated. I picked my copy up at Secret Headquarters on a recent trip to LA, on staff recommendation (I've never gotten a bum steer from SHQ). It's got me excited about Batman comics for the first time in 20 years.
