I watched this film a while back, probably in February or March but didn't write it down in my list and forgot about it. But I think it's one to blog about, you see it is not the worst horror film I have seen. The idea of it is good. A young couple are disturbed just as they are about to go to bed by a friend (David) who appears at their door. He has been recently left by his partner and the closeness of their friendship means he is welcome to stay and the two men spend the night talking. They seem to get very little sleep during the whole film. David is seeing evil monsters in the shadows but doesn't admit this to the couple at first. The way the threat emerges is handled really well. We, the audience, think the monsters must be just in David's mind. But by the end of the film they seem very real. It is a decent film but not a mainstream one and it does take a while to get going but I think that's excusable in this case and in the contemporary British setting of the film.
