It’s hard to find great horror movies that are also great love stories, because for the most part, those things are polar opposites. Many of the greatest and scariest horror movies ever made are all about ripping people who care about each other apart, literally and figuratively. The Shining may be terrifying but it’s hardly a comforting date movie, if you catch the drift.
But that doesn’t mean that horror movies can’t also be romantic; it’s just that they sometimes have to be romantic in unexpected ways. Tales of ghosts and demons who fall for mortal men and women have a tragic undercurrent but they’re often very sincere, and many of the most horrifying monsters ever conceived have a heart if you know where to look for it (and aren’t trying to shove a wooden stake in there).
