Communion

This film left a lasting impression on me, which didn't wane during the second and even third viewing. I have never thought about it as an "alien-movie". (Incidentally, the word "aliens" is never once mentioned in the film.) In my opinion, it is a film about the man's reaction to the inexplicable intruding into his orderly existence. It is all about people, not aliens. Each character has their own reaction to the strange. In fact, what we see is a "pilgrim's progress", with Walken fighting against various attempts (by others and by himself) to explain it away. It is a philosophical parable, saying that any explanation would be nothing but a mask over the truth, which cannot be expressed in words. As Walken says: "This cannot be it. I didn't come all this way for you to tell me that this is it."
