ppl need to watch the excorist to see wot makes a movie actually scary
lots of subliminal stuff happens, if it uses a sound to represent a feeling then the actor/actress doesn't make that big of a physical response but looks more shocked and like a real person would react, if they use a big physical response to represent a feeling or scary action then they take the sound out. This makes those suspense moments extra creepy and awkward.
Too many horror movies show something creepy, with loud music and with lots of expression in the actors faces and the film is basically saying "LOOK, A SCARY PART"
the excorist had scenes left out because of how scary and subliminal they were, like the faces on the walls when the mother is walking through the house, they appear like brad pitt does throughout the movie Fight Club, just quick flashes, they took those out in the original theatre release bc they were too mindfukking.
Also the scene where she walks down the stairs, it just happens with a loud shriek of music, and the mother has a blank horrified stare on looking like "WTF!" then the scene ends and it goes to the next day without explaining wtf you just saw, or why you saw it.
