What allows this movie to work so well was that everybody plays it completely straight. From the high-school students to the Vixens themselves, it's almost totally naturalistic. The only deviation from this is when a character will occasionally direct something to the audience as an aside, but that works too at the points in the movie where it happens.
The cast, although inexperienced, looked just like small town high school students and acted like them too. There was none of the false glamour you get in Hollywood movies about teenagers, and even the Vixens aren't really that drop dead gorgeous, more like heavily made up girls with lots of attitude.
The DVD comes with a few special features, a short interview with one of the Vixens, a deleted scene that's talked over by the directors, and an optional commentary track. I like the fact that nobody tried to fix up the original grainy print or the audio track — it adds to the overall effect of the movie and gives it part of its charm.
The Revenge Of The Teenage Vixens From Outer Space is a wonderful homage to all the movies we loved because they were so bad they were good. The filmmakers have managed the amazing feat of making a film just like them, with only the occasional hint to let us know they are in on the joke. It's not often you get a chance to own something this bad and be glad you do, so don't pass up this opportunity to own what will surely go down in the annals of cinema as a classic.
