Shawn Van Horn is a Senior Author for Collider. He's watched way too many slasher movies over the decades, which makes him an aficionado on all things Halloween and Friday the 13th. Don't ask him to choose between Michael Myers and Jason Voorhees because he can't do it. He grew up in the 90s, when Seinfeld, Everybody Loves Raymond, and TGIF were his life, and still watches them religiously to this day. Larry David is his spirit animal. His love for entertainment spreads to the written word as well. He has written two novels and is neck deep in the querying trenches. He is also a short story maker upper and poet with a dozen publishing credits to his name. He lives in small town Ohio, where he likes to watch professional wrestling and movies.

We all have those favorite shows we became quick fans of, only for the plug to be pulled just as it was getting going. Freaks and Geeks only made it one season on NBC, as did Fox's Firefly. In the last decade, fans are wary of falling in love with any series on Netflix, where shows like 1899, The OA, Santa Clarita Diet, and so many others ended early before we got resolutions to crucial plotlines. Perhaps the most famous of these great unfinished shows is Mindhunter. Produced and run by director David Fincher, Mindhunter lasted two seasons, only to be canceled right as a compelling storyline was being revealed for Season 3. Seven years after its last episode, its biggest fans still hold out hope for more episodes.

David Fincher's 'Mindhunter' Was a Critically Acclaimed Netflix Hit

Mindhunter is based on Mindhunter: Inside the FBI's Elite Serial Crime Unit, co-written by former FBI agent John E. Douglas, who gives insights into his profiles of some very terrifying real-life serial killers. The series first premiered in 2017 with Fincher directing four of the 10 episodes. His gritty filmmaking style is evident in a series that feels like The X-Files meets True Detective, where the tension is not found in solving murders but in a dialogue-heavy drama seeking to get into the inner workings of America's most evil murderers of the 1970s through protagonists going through their own darkness.

Mindhunter starred Jonathan Groff and Holt McCallany as FBI agents Holden Ford and Bill Trench, the former a young, troubled man with a new way of doing things, and the latter the aging veteran who wants to do things by the book. Along with psychologist Wendy Carr (Anna Torv), it's the job of the FBI Behavioral Science Unit to discover what makes these evil men tick. Imagine the scene of Clarice Starling (Jodie Foster) meeting Hannibal Lecter (Anthony Hopkins) in prison in The Silence of the Lambs as an entire series, and you're not far off.

Season 1 of Mindhunter had an impressive Rotten Tomatoes score of 96%. When it returned two years later for Season 2 in 2019, it was even better, now with a critics score of 99% despite moving away from the brilliant performance of Cameron Britton as the hulking serial killer Edward Kemper. The new batch of episodes focused mainly on the Atlanta Child Murders, with more and more scenes showing the horrifying evolution of Dennis Rader (Sonny Valicenti), known as the BTK Killer. What would happen next?

'Mindhunter' Was Cancelled After Just Two Seasons

Sadly, nothing happened next. Months after Season 2 of Mindhunter premiered came the news that Season 3 would be put on hold indefinitely while David Fincher directed the feature film Mank for Netflix. Then, in January 2020, came another unfortunate update as a Netflix representative told TV Line that Fincher "may revisit Mindhunter" in the future, but that seemed so far out that the streamer decided to release the actors from their contracts.

Years passed, and Mindhunter never returned. In 2023, during an interview with Forbes, Fincher put the blame for the series ending not on himself and his busy schedule but Netflix, telling the outlet:

"I'm very proud of the first two seasons. But it's a very expensive show and, in the eyes of Netflix, we didn't attract enough of an audience to justify such an investment. I don't blame them, they took risks to get the show off the ground, gave me the means to do Mank the way I wanted to do it and they allowed me to venture down new paths with The Killer. It's a blessing to be able to work with people who are capable of boldness. The day our desires are not the same, we have to be honest about parting ways."

What Would Have Happened in Season 3 of 'Mindhunter'?

No matter if Mindhunter's sudden cancelation is to blame on Fincher, Netflix, or a combination of both is unclear. What is clear, however, is what fans would have seen in Season 3. In 2022, Season 2 director Andrew Dominik told Collider:

"What they were going to do with Season 3 was they were going to go [to] Hollywood. So one of them was going to be hooking up with Jonathan Demme and the other one was going to be hooking up with Michael Mann. And it was all going to be about profiling making it into the sort of zeitgeist, the public consciousness. It would've been... That was the season everyone was really waiting for to do, with when they sort of get out of the basement and start."

Mindhunter is a hard loss to take for its fans because there are so many frustrating unanswered questions. Would Trench's son, who killed a child, have become a serial killer himself? What would happen to Holden, who was battling severe anxiety and issues with his wife? In 2025, Holt McCallany gave fans hope when he told CBR that he'd met with Fincher, "And he said to me that there is a chance that it may come back as three two-hour movies, but I think it's just a chance."

However, last month revealed that Fincher, who directed The Further Mis-Adventures of Cliff Booth for Netflix, is leaving the streamer when his contract is up. Fans will continue to hope anyway, and every year it doesn't return, the series only grows in popularity. If absence truly makes the heart grow fonder, Mindhunter is about as fond as it gets.
