The Z Warriors discover an unopenable music box and are told to open it with the Dragon Balls. The contents turn out to be a warrior named Tapion who had sealed himself inside along with a monster called Hildegarn. Goku must now perfect a new technique to defeat the evil monster.
Mainstream comedies should all be this funny and tender and deftly performed.
The directors Paul and Chris Weitz -- the American Pie brothers -- have tried hard not to make a tearjerker, and at its best the movie is knowing and tart.
Very funny and smart, its shot like a comedy and suffers like most comedies do because of it.
