Talk about another classic horror franchise. If you made people name the most influential horror movies, this would probably rank in the top five. They keep making these, which goes to show you that they touche a nerve. I think the main reason is that it's based on a true story. That always connects with people. I just hate when they tell you it's based on true events, but you find out that it's barely based on anything actually scary.
Here's an example. There was a movie called 'The Strangers' based on real events. It turns out that was just a marketing plow. The "real event" was that the producer's neighbor once got scared because someone knocked on their door. We could spend a long time roasting that person for being scared of a knock, but I'd rather give a big F you to the guy who decided to say that was a real event.
