Yes, the "Excorcist" is also one of those movies that is creepy scary. Kind of stays with you. Most scary movies nowadays are all about blood and gore and things jumping in from offscreen.
One of the best things about "Jaws" is that you don't get to see the shark until halfway through the movie. I think Spielberg made that demand. Or maybe it's just because they could never get the mechanical shark to work correctly. The original "Alien" is also a good example of one of those tension builders. In my opinion, todays audiences don't have the patience for stuff like that. It's all about quick payoffs. There are exceptions, don't get me wrong. I really enjoyed "The Sixth Sense," and I appreciated what "The Others" tried to do (the ending killed it).
