I am guessing I was at the same New Beverly Cinema screening as the other commenter, where the audience went from confused and generally amused to teetering on the brink of rioting. As has been previously stated, this is not a horror film. It is incredibly unique, however - the kind of bastard love-child of Antonioni, "My Dinner With Andre," "Death Bed: The Bed That Eats," "Peeping Tom," and the novels of Bruce Wagner. At the very least, it surely deserves a DVD release, for the jaw-dropping final shot alone.
There's a good Psychotronic article in here somewhere - feminist manifesto sold as a genre film, with a cast and crew that came out of nowhere, nailed the film, then all but vanished. At the very least this movie could be programmed with the likes of "Sorority House Massacre" on some kind of "lesser known Psychotronic women" bill.
Worth seeking out, but be warned: It's not a horror film, it's molasses slow, and it's one of film's true buried curiosities.
