I appreciate the sheer number of experts, input from detectives and almost-victims, and a number of family members and journalists -- they keep it varied and supply a lot of interesting facts on each killer, from childhood to imprisonment and death. Each episode makes a stand-alone documentary. I like Fred Dineage's background commentary -- his voice is clear and easy to follow. Unlike some of these true crime shows, they don't use the same shots over and over from one episode to the next. I've watched the first 7 seasons a couple of times, but can't find season 8. If you like true crime, this show will have many killers you've never heard of before.
