10. Amour
There are very things more inherently frightening than getting older and losing control of yourself. Amour deals with the innate humanity between two people who have been married for decades with its horrifying love story. The thing that sets the film apart from being a straight horror movie is the stark realness that Michael Haneke brings to his direction of his story. Everything is filmed so matter of fact that it eventually begins to feel less like a movie and more like a real struggle with age and commitment between these two people who have loved each other more than most people will ever know. Haneke's film also deals with euthanasia, which is hardly a topic that gets any attention in modern cinema but is used here to great effect. The morality that Amour struggles with is what seals its place on this list because it is something that can never fully be dealt with and is completely present in real life.
