Sorry Lou but I think you have it backwards. You're thinking its a documentary trying to be a mystery when it is a mystery. The difference being they're investigating causes of deaths related to attacks. They have investigators, forensics teams, other experts, etc trying to find out what happened. A documentary would just tag the animals to learn about them, film them, then deliver the results of study - hence the name documentary, as in what's being documented through study. This? Straight up mystery as they're investigating events as a primary goal. If you want a documentary, I'd suggest you click on the genre "Documentary" at the top of the page...
