Editing; Psycho

Today in class we watched the iconic shower scene from Alfred Hitchcock's Psycho. The director had used fast and frantic shots to make the scene more gruesome and scary than it actually was, as at no point does the viewer see the killer stab the woman. We see her reaction to the killer, the knife, the stabbing motion, blood around her feet, but we don't at any point see any harm being done to her, but we assume shes been stabbed to death due to the rapid edits.
