As a teen I was raised on these Skinemax kind of movies, so I have a soft spot for them...This was one I'd never heard of and it turns out to be a pleasant surprise. It does feature the usual beautiful women (I think I remember the blond girl winning FEAR FACTOR once) getting naked but there was actually a pretty good story in there too with alot of back-stabbing among the family to keep things interesting.
The movie is also well shot for a low budget with a certain slickness and style that are usually overlooked in these kinds of movies. They even make good use of the main location -- A cabin in the middle of the woods.
Too bad we never got a sequel since it seems set up perfectly for one.
