Most of us here watch many movies, PG, G, PG-13, R. There's always that one scene that will just creep you out, and you won't forget it for a long time.
That scene for me is the fight scene between Deckard and Pris from Blade Runner. When he shoots Pris, it looks like she's having a temper-tantrum while having a seizure... it's just so weird.
