Ever since Alien, I like my horror mixed with SciFi. John Carpenter's version of The Thing was classic. I remember my mom telling me she was scared to death seeing the original black and white version as a teen in the 50s. Seeing that old BW one now is kinda boring so each generation is redefining what is scary to them. So many to choose from. For me it was:
Night of The Living Dead, the orignal low budget, black and white one.
Phantasm
The Exorcist
The Omen
Rosemary's Baby
Alien
The Thing(1982)
Nightmare on Elmstreet
Hellraiser
Invasion of the Body Snatchers(1978) again, this was one that scared my mom in the original 50s version which looked pretty lame in 1978. I'm sure younger kids seeing the 78 version might think it was lame. The modern one with Nicole Kidman was good but not top 10 to me.
10 seems too short. What about Reanimator? This movie deeply disturbed me at the time that I saw it. It was so bizarre and disgusting. Not sure how it would hold up if I watched it today. The Shinning, Pet Cemetary, those were pretty good. The Ring, the Grudge, those types don't really seem that scary to me. Saw, Texas Chainsaw, Silence of the Lambs were disturbing and suspenseful, but to me not super scary in the horror movie sense. Well this was fun. back to work.
