Prevenge
This pitch-black 2016 horror comedy stars Alice Lowe (Sightseers, Black Mirror: Bandersnatch), who also wrote and directed, as Ruth, a pregnant woman who believes her unborn child is instructing her to wreak bloody vengeance on the people responsible for her partner’s death. The supporting cast includes Game of Thrones’ Kate Dickie and Gemma Whelan, and What We Do in the Shadows’ Kayvan Novak, and while you would not want what happens to Ruth to happen to you, Lowe manages to make her horrifying plight into a wickedly funny movie.
