If you are easily offended by nudity or swearing, maybe you shouldn't watch this. Actually you shouldn't watch this period! On the other hand it is one of the last (if not the last) movie you can watch the late Hopper and the late Carradine together in one movie. Of course there is one scene with Carradine that might make you cringe, especially if you know the circumstances of his own death.
But there is one other thing that might leave you baffled. It's the story. The fact that you might not be able to follow it through from start to finish. It doesn't even matter that you have a "McGuffin" in there (a very obvious one). What you do get, is a very confident and good Michael Madsen (QT producing might have again brought out the best in him, with a scene on a tree that does look very ad-libbed).
Overall this movie does have a fascination to it (a weird one, that has nothing to do with all the female nudity, though this might make the movie either more or less appealing to you). Not good, but not a bad one either ...
