First and foremost, I'd like to get one important disclaimer out of the way: horror is subjective. What scares one person may not even cause another to bat an eyelash. Whether your most terrifying scenario is finding yourself trapped in a wax museum or swimming in the middle of the ocean, it doesn't matter if it seems real to anyone else, because it sure as hell means something to us in the moment!

In 1978, the movie Halloween was released after being shot on a limited budget and a shotgunned script that was written in only 10 days. Trumping any doubts that may have been present, John Carpenter's tale of undying evil went forth into the pop culture lexicon as one of the greatest horror movies of all time. And its success wasn't achieved through buckets of blood and a waxed Burt Reynolds starring as Laurie Strode, but rather the prospect of what could happen and what couldn't be seen until it was way too late.
