I think I covered most of what you said. But your way of defining the key difference between Timothy and Werner is odd. It's more nature as benign vs. nature as hostile. Treadwell's pretense of a tame and friendly bear is false and dangerous. His behavior ultimately could make an anti-environmentalist of anyone. "Treadwell is a tragic figure in many ways." Really is that all you can come up with? It's more complex than that. Watch it again.

"Had Treadwell not had such an ironic death, then perhaps we might agree more with his views." No. But Herzog would not have made a film.
