Before I review this I wish the media would name serial killers with more appropriate names. He is not the raincoat killer but a frightened little man killer who preyed on the elderly and weaker females. The series reviews the case of a serial killer who unusually changed his modus operandi. It starts with a brief overview of the gap between rich and poor in Korea and the feelings of alienation of some in the early 2000's. I do not think this is relevant as many people I am sure had more deprived childhoods but did not turn into psychotic killers. Over 3 episodes it gives the timeline of the murders and uses talking heads of the people involved. It talks to the criminal profiler on the case and the detective's and prosecutors and also the brother of an early victim and most fascinatingly the female forensic head who amongst them all seems most empathetic. It is quite honest as it shows the crudity of police operations at that time and the only good to come from these horrific killings was the major improvements made in criminal investigations.
