I'll give this a generous two stars for the movie and four for the presentation. The plot is pretty threadbare and there are some absurd plot twists. It's closer to soft porn than a horror/thriller really, as the characters have a frequent tendency to get physical with each other. At one point Linda Hayden's character starts kissing Fiona Richmond despite the total lack of any kind of attraction or flirtation between them up to that point, while her boyfriend is in the house, and she enthusiastically goes along with it. It's that kind of movie.
Fiona Richmond was a "glamour model" and seems right at home here, but Hayden and Kier really seem to be slumming it. In the interview with Hayden included in the extras, she spends quite a bit of time bashing the movie, even saying it's the only movie she's ashamed of making. And she worked mostly in B movies that were often lacking in quality.
This is one of those discs where the extras actually were more interesting than the movie, especially if you can get a copy with the documentary about the Video Nasties scare. I'd heard of the nasties scare but had no idea how far the censors went, even raiding the homes of some movie collectors to make examples of them.
It really made me appreciate being an American. Yes, there's censorship here too, but it's never come close to going that far in my lifetime. The MPAA can be bad, but they don't have the ability to ban a movie outright and when it comes to the home video market, there isn't much government censorship. That's mostly limited to stuff that involves crimes being committed, like child pornography. Usually what happens here is studios will force filmmakers to make cuts in order to get a certain rating in order to play in more theaters or have a larger audience. The MPAA is actually not a government agency - the government's not directly involved. It's more a case of self censorship by the theaters and studios. And when movies are released on home videos there's no government board that reviews the movies to decide what they think is or isn't acceptable. You'll frequently see uncensored, unrated versions of movies, and no one has to worry about running them by the government before putting them out.
