It is a definite oddball film. It will subvert your expectations, which some people might not like. That said, it is wickedly chilling, and doesn't quite hit the creepy mark. You can also see a lot of Mamoru Hosoda's style seep through. I will say the animation itself looks almost incomplete at times, but it is charming and very fluid. Its great to see a progression in style as he would go on to make Summer Wars and Wolf Children.
