His use of staircases and bathrooms was really scary. This is still weak and would get a 2 or 3. It's very subjective and chatty. It lacks a clear thesis. The paragraph has little coherence.
Much more precision is needed.
I loved the way the film creates suspense and involvement effectively. Hitchcock does not just scare us or show us horrible things. He involves us with his characters and shows how there is something sinister in all of us, even as viewers. This is better. It might get a 4.
