I guess ya gotta be kind of 'morbid' to watch it... it's about serial killers. It's fiction BUT... based on real cases with real facts. VERY true to the facts... in fact the 'interviews' shown in the series are almost verbatim transcripts of the actual interviews with the serial killers.
It's rough... some of it almost unbearable to watch... and not just the descriptions of the murders, (although that's the worst), but also what they have to do to coax answers out of the killers. It will make you want to reach thru the screen and strangle them yourself. Guess that's a contradiction, huh?
If you did watch I have a question for you, by the way. - JamesJM
