Pet Sematary was the scariest for me. The whole movie just creeped me out and I only watched it once. I wont even watch it when they show it on tv and then all the gross stuff is cut out. Its the creepiest movie of all time. And the music adds to that.
I think The Descent is my favorite horror movie, too. The sequel, The Descent II, is equally good, which is rare.
The scariest movie scene I ever saw was in The Descent when one of those creatures sneaks up on them and Sarah sees it through the lens of the camera. I've seen that movie at least three times. I always jump at that part.
Alfred Hitchcock's Psycho....to this day, I cannot take a shower with the shower curtain closed all the way.
Man, I'm not sure why, but ROSEMARY'S BABY always gives me the chuck-horrors...not so much the devilish stuff, that's old hat, but the claustrophobic feeling that EVERYONE is out to get her...how everywhere she turns she finds another fiend secretly plotting against her...it drives me nuts!
I agree with those who posted on being totally creeped out by the herky-jerky creepy as heck movements. The Grudge is the movie I'd say that has scared me the absolute most, I still freak out thinking about it, and that was a few years ago. When I'm home alone at night, I'm always glancing up the stairs, afraid that the woman is gonna come crawling down them.... ugh, freaky, freaky, freaky! The Ring scared me too, but not as bad as that lady from the Grudge... And my friends would call me when I was alone at night and make that noise too... punks.
Favorite scary movies though, as far as re-watching, I really like the Dawn of the Dead remake and the Texas Chainsaw remake, and the Wrong Turns, and the Hills Have Eyes, and the Saw movies and the Hostel movies... I'm a sucker for the gore, I guess there's some sick part of me that likes seeing people being tortured and mutilated... NOT that I want to see that stuff for real... ew, no freakin' way, sick... but in a movie, hells yea.
O yea, and I forgot to add that I love movies (and fiction) set in old mental hospitals... so creepy, and yet I compulsively want to know and learn more about them...
I'd probably have to say An American Werewolf In London. Saw that when I was young. Kinda freaked me out. Also I quite like Evil Dead 2. But in all honesty I'm not a big fan of horror (even though Stephen King is my favourite author, lol).
Yes Descent was tough going even before the actual horror element commenced! Then the scene at the end of Carrie in the house with the Mother, the night vision scene in Silence of the Lambs... Not a horror but theres a scene in the last or it might be the second last episode in season one of Homeland where I didn't breath for two minutes.
I LOVE that movie! The Others is one of the most understated horror films of the last twenty years. Glad you enjoyed it. Might I also suggest the 1980 film The Changeling with George C. Scott? It is similar in theme and execution and stands as a lifelong favorite.
