Warped movie

This is a really messed up movie. There are some scenes that are very off-putting that hint at an incestuous relationship between Norman Bates and his mother. Some scenes hint that Norman is sexually aroused in the presence of his mother. Twice he has an erection when he's with her. There is one sick scene when Norman is literally groping his mother's leg. In the same scene they are rolling around on the floor like lovers. The way the movie was made you would think that she wasn't even his real mother and that's why he had such feelings for her, but the movie never says this. I think Joseph Stefano did a good job writing Alfred Hitchcock's Psycho, but I think he really lost it when he wrote this. I really think he came off looking like a perverted old man. I don't know what they were thinking when they made this movie. This movie is very weird and very warped. This movie or any of the Psycho sequels should not even be mentioned in the same sentence as Hitchcock's Psycho.
