While it's pretty obvious that this film was done on a low budget (i.e. the same shots are repeated over and over and over) this is a pretty effective horror movie and deserves a look. The death scenes are well executed (and the end is quite chilling), the music is appropriate (it's sounds almost like an "angry swamp"), and the locations are put to good use. It's definitely a b-movie and is not at all "great cinema", but it's still a minor classic and should have some kind of cult status.
