This fictionalized show about the development of 1970's police forensic psychology and profiling is brilliant. It takes a premise, which could have been a documentary, and develops it around fictional and real characters. The scripts and storyline is brilliant. The acting by the main characters, especially the two leads, is fantastic. The Direction by David FIncher and others is movie quality. The 1970's attention to detail is just stunning. The interweaving of the brilliant role outs of real serial killers is just amazing to watch. The people and the scripts surrounding Manson, the Co-ed Killer, BTK, the Son of Sam and more are just fascinating. The is a thoughtfully constructed show and one of Netflix's finest additions. I wish I had watched it sooner.
