As stated earlier, there are only so many times one can watch a Japanese guy fall out of a tree. The slapstick in this is of such a desperate and unpleasant quality, it'll give you a headache. BUT...
If you are looking for reasons to watch, they are as follows:
Opening credits. They are painted on giant plywood rabbits that were placed outside and then filmed. It makes for a colorful and crazy opening.
Arch Jr. The guy actually shows some star power here. Casual and cool-looking, unfortunately he isn't in it very much. He sings only one song.
Last and not least: The girl, "Jackie". She is totally cute. Just gorgeous and photographed very well. Sort of Natalie Portman-esque in her charms. Why never in another film??
