Apparently there were 2 Japanese films of the title "Colorful". Everyone tells the synopsis of the excellent heaven-can-wait live-action fantasy that was released in 2000. It's about a boy's spirit who killed himself. He returns in another boy's body for redemption. This was shown at some festivals. It was family friendly and got good reviews. But then stores sell/rent you a stupid anime of men drooling over women's panties. Believe me I've tried. The bad one is anime from ADV films. It was released in 2005, on DVD-only release, with 16 episodes of bad sex jokes. If someone can get the correct non-anime Colorful, please let me know!
