The artwork is a stunner in this graphic novel volume, however the story is rather incomprehensible. It's hard to track what's going on, seeing as how there are two different Batmans and Supermans (technically one is Superboy), and their behavior was different from what you expect from the character...

Would seriously recommend two or more reads of this, just to get a clear take on it.Not the simplest of stories to follow, but truly epic, with fab artwork.
