Mindhunter

"Mindhunter" (2017-2019) delivers a chilling dive into criminal psychology through the FBI's early behavioral science unit. Set in the late 1970s, the series follows agents Holden Ford (Jonathan Groff) and Bill Tench (Holt McCallany) as they interview imprisoned serial killers to develop profiling techniques. With David Fincher's signature atmospheric direction, the show explores the origins of modern criminal profiling through unsettling conversations with killers like Edmund Kemper. Its slow-burn tension comes from psychological depth rather than graphic violence, offering a cerebral take on true crime. Though abruptly discontinued, its meticulous character studies and historical accuracy made it one of Netflix's most sophisticated originals.
