I never would have seen this movie or known of it's existence without my kids. My daughter showed me a clip from the first 10 minutes, and I was hooked, because I had to know what was going on. From then on, it was silly and juvenile but every now and then very unexpected things would happen. I'm not sure if this is deemed a horror or sci-fi, but the Japanese film industry sure is different, and occasional worth diving into. I'm glad I watched it, but wouldn't necessarily recommend it.
