The subject matter should be interesting however the narrator and the "experts" are insanely boring which makes it difficult to focus on what they're actually talking about. Aside from the numerous factual errors, it's difficult to listen to these people blather on about things that they seem to have picked up directly from various made-for-tv movies. Try giving "City of Angels: City of Death" a watch for a far more interesting show on serial killers. "Becoming Evil: Serial Killers" was just a snooze-fest.
