I picked up this movie mainly out of curiosity. The front of the box looked interesting and the back only featured a long list of bands whose music is used in the movie; no mention of actors or plot summary. In many ways, it's a very typical 80's party movie seeing as it features:
i) a weak plot- this is the strange thing about a lot of 80's movies. The plot is so weird it totally blows any chance of the movie focusing on character development or virtually any other element. This particular movie is about a nerd (played beautifully by Eddie Deezen) who is trying to get revenge on surfers because they spiked his cola back in high school. His plan is a new drink, "Buzz Cola" that is designed to turn its drinkers into punk rock zombies.
ii) formula characters- another great feature of 80's movies. You've got suffer dudes, loose girlfriends, a fat guy famous for his eating ability, an evil genius nerd, zombies who look like George Michael from his leather days; etc. Deezen is probably the best cast of the bunch.
iii) female frontal nudity- show me an 80's movie without T&A and I'll... well, I don't know what I'd do, I doubt such a movie exists. It isn't exactly gratuitous here so don't expect a softcore porn fest.
iv) gross outs- from eating contests involving engine parts and dead fish, to an autopsy and a sandwich filled with "special" sauce.
All that being said, this movie is a lot of fun. It's a good movie to put on at a party because I'm sure alcohol would only add to its appeal. If you get a chance to cheaply rent it or buy it, it's no worse than a lot of other movies made around the same time. Give it a whirl.
