RE: Hoping for a good scare!!!
I've always been of the opinion that "less is more" when it comes to scary movies. The great thing about The Exorcist is that you never actually see the "monster" (the devil). It's left to your own imagination what it really is. Plus you never knew WHY the devil decided to take Regan.
As a kid I remember staying up one night and watching "The Legend of Hell House" (I think that's what it was). I remember almost nothing about it, EXCEPT this one scene where a woman is lying in bed and something is POUNDING on the door. I mean it was like thunder. We never got to see what was doing the pounding, and I remember it scared the PISS out of me. I had to sleep with my bedroom door open and the hall light on for weeks.
I absolutely loved the first half of "Poltergiest", because you didn't really know what was behind all of the strange things happening in the house. You could almost imagine it really happening somewhere. But then it got downright silly, with the esophagus-thing in the closet and the coffins exploding out of the ground.
Nowadays, it's all about being able to show anything, thanks to CGI. Some guy can create the devil in all his glory on a workstation. But it's nowhere near as scary because you know it's an effect. The mind is much better at conjuring up horror on its own.
