Oh, a short anime film that isn't by Yoji Kuri? That's automatically a step up.
Story: While the story is very simple, it's still quite engaging for a silent short film. I actually found myself getting creeped out a bit by what was happening.
Animation: If you're looking for typical anime then you won't find it with these short films. I'm actually quite impressed by the quality here, this sort of stuff is not easy to do and there is clearly a lot of effort put into it. I also love how innocent it looks at first, it kinda throws you off guard.
Sound: The music can be a bit annoying. It starts off rather light hearted but that changes with the story. I didn't really care much for it though...
Character: The killer family is fucking creepy. I didn't think claymation characters could be so scary... I actually found myself rooting for the girl to make it out alive.
Overall: I'd say this was five minutes well spent. While it's no masterpiece, there is clearly a lot of effort put into it and it's entertaining enough.
