Pop culture educated people under fifty probably wouldn't know a horror movie plot if they fell over it. The junk that passes for horror movies these days and for the past couple of decades is nothing but realistic blood letting and digital action not unlike a video game. It's interesting to note that director George Romero changed the face of zombies forever in his low budget "Night of the Living Dead" hit, shot for about a hundred bucks in a New Jersey farmhouse. Before Romero's version of brain hungry cannibal zombies they were seen as stiff legged corpses that killed only at the direction of a master (usually Bella Lagosi). Hitchcock's movie "Psycho" (loosely based on a real life character Ed. Ghein) was so well done that most people would swear that they actually saw the female character being stabbed in the shower but they didn't.
