I bought this on the Amazon market place for 1p, in "good" condition. I enjoyed the film because it was quite different to the stuff that is around today. Instead of being soaked in guts and blood, it plays on your nerves with chills and jumps. The acting isn't bad and the story is entertaining, the creatures are what make this unique, you only ever get flashes of the monsters, you don't really get to see what they are, and this provides some great jumpy moments, for example; there was a great scene when a woman looked down an air vent and we see a dark creature crawling around in the distance, it then suddenly jumps at the screen- the tension is great and the creature is very spooky. Unfortunatly, not all of the film is this good, although having these scares that keep the film exciting, many scenes are a bit weak and the characters aren't developed well enough for you to care much for them. But, if you like this sort of horror, not the gorey stuff, then this is enjoyable and certainly worth 1p.
