How bad is it? It almost looks like a high school project.
Should you see it? Not really. It's hard to find, anyway.
This is one of those films where they take a great title and try to make a silly movie out of it, playing it straight. Sometimes that works; here it doesn't. A mis-delivered catalogue causes a planet of women to come to Earth seeking men. They seduce essentially every male in a high school, upsetting all the girls and finding that Earthlings are disappointing lovers. So they turn them into vegetables - literally: they become things like squash. The ending is a truly awful "homage" to "The Wizard of Oz," as they click their ruby heels and head for home. The film was shot mostly in 1981, with additional footage in 1985 (and people's looks changed) and stars people who never made another film. The actors look only slightly too mature for high school. The special effects are close to non-existent, which isn't surprising for a reported budget of around $30000. This used to show up late at night on the USA network and had a brief release on VHS.
