The sound when Rob falls on to of the car with a crash, the sound is base boosted.
Rob rolls across the car, and lays dead on the hod. But in the shot where one of the devils is staring at him, he is not there on the hood.
At the end when one of the mountain devils attack the camera man,it flies into the car, but yet the car window is rolled up.
The sounds of the mountain devils crying are all the same.
