National Geographic went to shit when it stopped being about animals.
It's as though finding intact WW2 vehicles and weapons that aren't in a museum or collection and then getting permission to get them dirty and destroyed is kind of hard to do.For most viewers, a gun is a gun and a tank is a tank. It's considerably more expensive to get ahold of WW2 equipment (Or make replicas) when the vast majority of people don't honestly care in the first place. Though, granted, these are a lot more egregious than what you usually get. Documentary channels have been going downhill for a while now.
