Clearly, the best horror film ever made. I have never seen a movie with so many tricks and surprises pulled off in a successful manner. I was so involved with Janet Leigh's character when I first watched this film. Yet I knew she was doing something wrong. Suddenly when her final destination is at hand, I was purely surprised. Then suddenly, I'm pulled into the world of a hermit-like motel owner who cares for his invalid mother. I see no mistakes or bad moves in this film, and the performances are excellent. 10/10
