This is just a simple example that shows how terrible and absolutely LAZY this series is. In one of the episodes they claim that some of the people were living with serial killers. Any self respecting documentary would show police reports or any real life factual evidence that anything these people are spewing out have any bearing on reality but instead it just allows these people to blabber on about how their dad was a serial killer like if it's no big deal. Show us some follow up or evidence so that we can take anything you say seriously!
