With Halloween tomorrow, my girlfriend and I decided we'd like to stay home and try to scare ourselves shitless with some scary movies. Problem is, neither one of us watch the horror genre nor are we fans of gore that modern horror seems to love so we are at a loss of what to watch. Only thing we can come up with is Poltergeist, which she hasn't seen so we'll be starting with that. Then I was thinking The Exorcist since it's been a decade or so since I've seen it and I remember it scaring the hell out of me, but I'd like 2 or 3 more to make sure we don't run out of scares and I'm out of ideas.
If you could recommend one scary movie to people who don't watch scary movies that was minimal in gore and will make us turn the lights back on, what would it be?
