The American crime drama web series, Mindhunter, debuted worldwide via Netflix on October 13, 2017. Based on the true crime book, Mindhunter: Inside the FBI's Elite Serial Crime Unit, by John E. Douglas and Mark Olshaker, the American web series takes place in 1977 when criminal psychology and criminal profiling were arising from its early developmental stages. While challenging the status quo of Means, Motive, Opportunity (MMO), two FBI agents, Holden Ford (Jonathan Groff) and Bill Tench (Holt McCallany), work in developing a new field incorporating psychology, sociology, and anthropology through the interviews of imprisoned serial killers in order to comprehend why they do what they do in hopes of using this knowledge for future and ongoing criminal cases. Because having a simple MMO is no longer sufficient. Crime has started to become more complex as well as inexplicable and irrational. All of which needs to be explained and rationalized to the normal human mind.
