What a disappointment. The facts are slim. Old movies are passed off as representations of the crimes. In the Jack the Ripper segment, for example, we have lengthy scenes from inaccurate 1930s films. But by far the worst is the stupid music (that screech from "Psycho") and the even stupider, more banal narration.The "experts" who tell us about the killers are strutting, preening dolts who think that putting a label on something (e.g., the urge to kill) explains it. The killers are psychopaths, sociopaths, we hear from the self styled scholars of crime. So what? That doesn't explain anything or add one iota to our understanding. It would be better to leave all that out and just give the facts. I've seen TV programs that do a far better job of telling what happened.Skip this set of DVDs. Someone will surely do this subject better.
