Horror movies aren't what they used to be. Things like ghosts, zombies and vampires don't scare people any more. Modern "horror" movies seem content at being thrillers ("I Know What You Did Last Summer"), or pastiches ("Scream"). But are people really less scared today than they were 30 years ago? Or are they just scared of different things? If so, what are they scared of? What is needed to make a story really scary to today's audience? EDIT: After posting, I realised this thread probably belongs in Plot Creation.
