Netflix and Blumhouse Television, the studio led by horror producer Jason Blum, have quietly built one of streaming's most popular true crime properties, the "Worst Ever" franchise. What began in 2022 as the five-episode docuseries Worst Roommate Ever has grown, four years on, into a three-series franchise spanning 21 episodes, with the spin-offs Worst Ex Ever and Worst Neighbor Ever. The article argues this run marks Blum, already regarded as a leading figure in modern horror, extending his influence into unscripted real-life crime storytelling.

The franchise pairs classic true crime techniques — first-person interviews and stylised reenactments — with hard evidence such as body-camera footage and 911 audio, presented in a short, easily binged format. Worst Roommate Ever grew from a viral 2018 New York Magazine article about serial squatter Jamison Bachman and earned a 100% Rotten Tomatoes rating. Worst Ex Ever featured high-profile cases including "Deadpool Killer" Wade Wilson and 90 Day Fiancé figure Geoffrey Paschal, while Worst Neighbor Ever focuses on disputes between neighbours that escalate to devastating ends. Netflix has not confirmed how the franchise will expand further.
