What can you say about the film "The Birds" by Alfred Hitch?

The Birds actually has no score - or soundtrack - at all. I think this makes the film effective, actually, because the only thing you hear when there is a silent moment on screen is birds in the background. This is very creepy; they're always lurking around. You hear their chirps, their flutters, their movements... creepy. You get the feeling that they're watching you.
