Should you see it? Only if you're a huge fan of the genre.
Chinese (Taiwan, not Hong Kong) versions of Japanese genres tend to be awful. This film involves a lot of little boys peeing, for some reason. It also involves werewolves and ninja bikers. Kids get turned into animals, but one ends up with an antenna and then later becomes a superhero who then fights an endless array of goofy bad guys. You know... the usual. The plot doesn't work because the bad guys aren't bad enough and they're easily dominated by children.
