Reenactments of real-life mysteries can be creepy.
Parents need to know that this series' entire focus is on unsolved crimes and other incidents. Many stories describe illegal -- and often violent -- behavior, while other episodes deal with missing persons and supposed supernatural phenomena. Reenactments sometimes include guns, gunfire, and visible blood. While these images aren't as graphic as what you'll find in similar contemporary shows, the show's sporadic violence and frequent creepiness are probably enough to give most parents pause.
