JLA: Ultramarine Corps - Grant Morrison

I keep trying to find something of Morrison's work from the past few years that I like and I keep failing. At least I'm consistent. The Ultramarines are a group of nobody superheroes who live on a floating city and get their butts kicked by everyone’s favorite super-ape: Grodd. Some sidekick who is also a genius gets Batman, the only member of the JLA not in another universe, who unleashes his robot versions of the JLA. I would think this would have gone over better as a kid’s comic except there was too much violence.
