How bad is it? Well, the title's misspelled, for one thing. It's alright.
Should you see it? If a Taiwanese children's film is what you want, yes.
If you want to see a bald child martial artist, seek no further. It's a story of a boy pursuing a girl, only to find that his female friend/sidekick is the one that's right for him. This film was recommended as an example for Chu Yen-ping's films, which have a reputation for weirdness. There's a video game that comes to life. There's firecrackers in a bed as a prank. There's a lot of juvenile humor. It's not bad as far as kid's films go - I mean, look at "Mac and Me" or "Nukie," for example.
