The story, and the re-imagined versions of each character are pretty interesting. The main character, Robin Drake, is sent out to warn the world that the evil creature that was thought to be dead has come back. Along the way he encounters his fellow JLA members in their own modified roles, and receives help in his quest.
The book tends to focus on a small handful of characters leaving the others with not a lot of time, and because of the different interpretations I would have liked to see a little more of each character.
I like the idea of a bunch of artists collaborating, and the end result is amazing.
