I watched a film this week that was made in 1978, a film called Prey. An alien lands in England and takes on human form after attacking a young couple directly after landing. He is then found and taken in by two young women living in a large, isolated country house. The two women have a strange relationship, they are lovers but one of them is quite overpowering. The more normal of the two suspects that the other has murdered her boyfriend. It's a very strange film, not scary at all. The make up effects are quite crude. The best part of the film are the relationships between the characters, there isn't a lot of action otherwise so its probably a good thing. The ending, which I won't spoil here, is a bit of a disappointment.
