Dreamy horror, full of deserted buildings, surreal sets, a progressive rock soundtrack and blood. All these elements are wonderfully realised, giving the film an excellent tension, although the story seems a little confused and the acting, every now and again, stultifying. The violence is nasty, although this goes with the territory. An effective piece, all in all; at least it would have been if only the story and direction could just have been given a little more of a leg up over the grisly set pieces.
