I think DC has kicked Marvel's butt in the animation category for a while. Batman, Supes, JL, to this new stuff.
At least DC is getting something right
But this is a must have - I think it will be worth the purchase. It is an origin story that hasn't been forced down our throats as others (Spidey, Bats, Supes) so I think an animated / straight to video release is apropriate.
