I felt like this documentary focused more on the private lives of the investigators than the killer and the crimes. Too many useless information such as the conversations that Gill had with his wife and what they had for breakfast, no offense but I really don't care. I felt that they could reveal more information about the killer's family, his childhood, whether he had friends, what he said during interrogations, his life behind bars etc. In the documentary they didn't even mention that he got married in jail. For example Ted Bundy's documentary was way better and portrayed the serial killer entirely.
