Häxan
Grave robbing, torture, possessed nuns, and a satanic Sabbath: Benjamin Christensen's legendary film uses a series of dramatic vignettes to explore the scientific hypothesis that the witches of the Middle Ages suffered the same hysteria as turn-of-the-century psychiatric patients. But the film itself is far from serious-- instead it's a witches' brew of the scary, gross, and darkly humorous.
Häxan is built around witchcraft, possession, and demonic imagery; horror is central to its identity, though it mixes pseudo-documentary elements, historical commentary, and dark humor.
Best for viewers looking for a scary, atmosphere-heavy, psychological and slow-burning horror movie.
