To be perfectly honest what this movie misses most is a game controller. The movie consists of good action scenes great boss battles and over the top weapons and abilities. Why then do I have to sit still and watch instead of actually engaging in the battles?
The plot of this movie is nothing to write home about. You have seen it in one form or another a million times before, often better executed. Would've done nicely for a game though.
The artwork however: sublime. I really doubted in the beginning of the movie whether it was animation or live action (other scenes are less convincing but still). The ruins of New York look like a delight to wander around in and to just explore.
I can honestly say I watched this movie for the art, not the story.
