I've yet to see a "scary" movie really that I liked. They're all more like "startle" movies. Let's make this scene reeeeaally quiet and then flash something on the screen with a loud sound! That'll make a scary movie! Umm, no, it doesn't.
See Jaws in a theatre, if it ever comes back. Yes, there is the startle element, but the film really built suspense time and time again, sometimes released, sometimes a fizzle, but it kept you on the edge of your seat throughout. By today's standards the special effects weren't very good, but that film was a suspense masterpiece.
