An American Werewolf in London (somewhat campy, I know) was the first horror movie I ever saw AT the theater. Everything else up until then I had seen on cable on a television.
AAWiL scared the ever-loving dog-crap out of me
because I saw it at age 14 when those effects were the most state of the art 'real' (i.e. not CGI, not stop-motion animation) effects. And it didn't help that I lived miles from town, so when my bud dropped me off at my house in the dark and with woods surrounding me, I literally
ran to my front door. Yes, that movie did it's job.
Not long after this one, I walked out on the movie
The Beast Within. That was just a sick movie. I didn't like it at all. And I still don't care for the gross-out rip-'em-up slasher flicks.
A couple of remakes I think they did a great job with:
John Carpenter's The Thing: missed this one at the theater; saw it on cable. :zombie: Still scared the bejeezus outta me! LOL.
The Fly... weird, crazy, suspenseful, scary, wonderful movie. Loved it!
Loved
Sleep Hollow too. Though not sure if I would call it 'horror'. Great imagery in that one of course with the cast and crew involved. *two thumbs up*
And years later I finally saw another horror movie at the theater that shook me to the core:
Event Horizon. There was just something about that flick that scared me badly. After the movie finished I felt like I was a frail, scared 14 year old again.
