I saw it last night... (accidentally posted another post in main forums http://www.killermovies.com/forums/f2/t412645.html).
I thought it was "good." The animation style was incredibly unique and amazing. However, the movie itself lacked "something," maybe it was more of a sci-fi element of just a stronger story, but it lacked. I did enjoy it, thought it was good, and have to see it again a second time to really consider its implications more... but overall good, not great.
