Moon Child is a 2003 Japanese film about how some criminal children befriend a vampire. He hangs out with them while they grow up. There's plenty of gangster posturing and not much else going on other than some melodrama. A lot of it seems pointless and uninteresting to me. I wondered how it could have a 6.6 on the IMDb with nearly 1900 votes but it turns out that 527 of them are a 10. That's some crazy shit. Another one I should have given a miss too.
