If you are looking for old-style nudity and near-porn, but still care for a decently amusing plot, you can't go wrong with this movie. It must have been pretty obscene at the time of its release, but now it should be no more than regular for the current nude-fan. If you are looking for a great, memorable movie, this is not it. But then I guess you knew that already. I didn't.
I started watching this movie with no expectations whatsoever. I knew none of the actors, nor ever heard of the previous title. I found it amongst my roommate's stuff, and having nothing to watch, put it on. Well, at the first inexplicably long, gratuitous and counter-plot sex scene, I understood the kind of movie this was...
Now, considering that the movie's purpose is to hump the viewer's leg, which lowers any intellectual expectations, the plot is decent enough actually, and the acting not that bad. So I watched on. There is just enough of character depth and development, story realism, and suspense, to justify the time lost watching it. Even when one of the characters does some weighing on life and death, flash-backing on events known to us (including, of course, sex scenes), which feels too fake and forced in the story, you tolerate it, because you know the movie isn't trying to pass for a master-piece.
Needless to say I skipped all the annoying sex scenes. These go on for minutes at a time, completely irrelevant, and a couple of them difficult to place in the plot (are they mere fantasies or did they really happen?).
So, this is an honest, "nice" movie: it will be evident soon enough that it is about soft-porn, but it comes with the bonus of a minimally entertaining context-story.
