I mean, you get the most basic facts on a large number of serial killers, and that's fine. Then you have the "experts" on nature and nurture saying the exact same thing at the end of every episode: There's the absolute clown criminologist David Wilson, who thinks socialization is the be all and end all of a phenotype, a theoretical paradigm that was already obviously wrong-headed in 2005; and then you have forensic psychologist Helen Morrison, who is supposed to be the nature expert, but all she ever talks about is "mutations" driving serial killer personalities. It's as if she doesn't understand the concept of heritability at all. I won't go into how the question of nature vs. nurture as it is discussed in this series is entirely nonsensical, just read a book on behavioural genetics.
So it's basically what you'd expect from a pulpy 2005 documentary series that crams everything on a serial killer into 45 minute episodes. The only reason to watch it is the sheer number of abridged biographies.
