Some of my favorite comic book writers... Gaiman, Max Landis, Warren Ellis, Chuck Dixon (all-time favorite Batman writer)... All great storytellers... All equally Grade A butt crevasses.
He's not a favorite of mine, in fact I hate his writing, but I've always been kind of surprised Mark Millar has never been embroiled in any weird sheet. Everything about him just screams "I'm a sketchy dude who does sketchy things."
