The artwork is cool; its nice to see real(?) drawings again in an animated film and the direct-to-video collaboration between Warner Bros and DC Comics has gotten good reviews. But sadly I must say that the story really does'nt hold up all that well.
They try to make it philosophical; and Batmans evil alterego Owlman is quoting Nietzche but acting like Schopenhauer on drugs. 'Every choise makes an alternative world; infinite worlds. The only real choise is to destroy them all.'
The whole consept plays like a materialistic version of the whole rebirth thingie. You are not born with your soul; but with your body and powers - your personality can be anything. Superman can be the evil Ultraman - Batman easily becomes the twisted Owlman.
Damn, I wish I was'nt born on a world this fucked up.
