I was definitely hoping for more. I was most certainly not expecting the plot of "Brotherhood of the Wolf" a movie released in 2001. Which by the way is a very entertaining movie, much more so than this "documentary".
There were some annoying factual errors in the show.
First the narrator states, at least twice, that the beast gave rise to the werewolf legend. The Beast of Gevaudan killed in the mid 1760's. Written werewolf legends have been around since at the very least 1st century A.D. Rome. Unless of course you count the Epic of Gilgamesh which has brief mention of a man turning into a wolf and hails from the 7th century B.C.
Second it is stated in the show that the beast was killed by a silver bullet, giving rise to the idea that silver bullets could be used to kill werewolves. Again a much older idea, which is probably why a silver bullet was used, it was the accepted method to kill werewolves according to already existing legends. If you think you're trying to kill a werewolf, then you go with the folklore you grew up with.
Finally at the end they did some interesting and pointless testing of ballistic performance of silver bullets vs. lead bullets, using a Marlin lever action rifle chambered in .444 Marlin. The ballistic characteristics and precision of which bear almost no resemblance to the black powder muzzle loading firearms of the mid to late 18th century. However they did get it right that silver is inferior to lead as far as terminal ballistics go. Still I would not volunteer to be shot with a silver bullet.
All in all I was disappointed. The show seemed to prefer to focus on the differences between the police officer and the cryptozoologist and their individual takes on the case. Instead I would have preferred to see a greater emphasis on the actual case itself and the effects on the surrounding countryside.
