Most movies go for the feel-good ending. Comedies are meant to make us laugh until the end. Dramas often see protagonists make up. Thrillers and action movies have the good guy conquer the evil villain. Horror is different. While the genre has its share of happy endings, where the final girl slays the killer or the monster is defeated, it's also the one that can get away with terrifying endings. Here, the antagonists are either victorious or the hero is so damaged that there is no true victory for them. Movies like Rosemary's Baby, Night of the Living Dead, Midsommar, and Smile knew how to scare the viewer through the very last second, but these 10 horror movies did it better than any other.
