Boring.
But good. It'd be better if everything wasn't (especially the characters) traced, and if they were drawn free-hand, atleast come up with your own original characters. It probably got better by the end of the movie but my attention span is very low (I need blood and violence, or something VERY artistic and well-drawn, or just humorous).
The action scene at the beginning was nice, though. And the voices were horrrrible. Which was kinda funny.
