I love the unique animation style and find it really entertaining. Odd, yes, but that is part of the appeal. Bizarre title song. Also fun as hell. Give it a rent, if not a purchase!
I just listened to the complete soundtrack again tonight, and it's not just the title song that is odd. The whole score is weirder than hell, but completely unlike anything else. I like different, especially in a world of conformity and blandness.
