Some early horror films have disappointed (sorry, but "Night of the living dead" didn't do it for me), and many of David Cronenberg's films have missed ("Scanners" being the king of the "Oooo, that was so close!").
This film, strangely, works on both levels: it is a good, older horror, and it is a good David Cronenberg film.
The low budget is obvious, but does not overwhelm the film. David Cronenberg's bravery to go beyond the "decent" is to be commended, as he ended up creating something more believable.
My only real critism of the film, is that for a film about sex crazed people, there is very little sex (pretty much none), and very little nudity.
That aside, this is a solid, creepy horror. Recommended.
