Psycho

Why it matters

This film still punches above its age because one scene became permanent public property: the shower attack. Plenty of people who never watched the full film still know the curtain, the knife silhouette, and the screaming strings. That is serious cultural penetration. It also helped shape modern horror and psychological-thriller language for later films. I am not ranking it this high because critics say it is great. I am ranking it here because the motel, the mother problem, and the shower scene are still all over jokes, spoofs, and fear language. Quite siao influence, honestly.
