The Mindhunter series will be based off the 1996 book Mind Hunter: Inside the FBIs Elite Serial Crime Unit by Mark Olshaker and former special agent John E. Douglas. The book tells the backstory of Douglas methods for profiling and catching some of the most notorious serial killers, like the Atlanta child murderer and the Seattle Green River Killer Gary Ridgway.
Shows set in a long gone period of time. Even if that time happens to be the 80's. Basically everything not taking place in the present of the time of filming.
These are all my favourite shows! Either they're practically faultless or are head and shoulders above the rest of the shows I've watched and enjoyed over the years. I highly recommend watching all of these!
