When Mindhunter debuted on Netflix in 2017, it became an immediate hit. For two seasons, David Fincher's psychological thriller followed two FBI agents tracking down the worst killers. Mindhunter ended much too soon in 2019, but if you're searching for something similar and missed out on it the first time around, check out HBO's The Outsider. The 2020 miniseries is an adaptation of Stephen King's novel of the same name. It follows two detective-types as well, played to perfection by Ben Mendelsohn and Cynthia Erivo, as they come face to face with a different, even more terrifying kind of killer. Produced, co-directed, and co-starring Jason Bateman, The Outsider only needed one season to tell its shocking story.
