I respect your uncertainty and it's shared by Herzog, except for the one point. I think it's very clear from Herzog's previous history that he's very attracted to and sympathetic toward quixotic, deranged, marginal people, as shown by his working with Klaus Kinski so often and with Bruno S. as Kaspar Hauser; and that Herzog perceives a kind of extraordinary quality, a saintliness, in Treadwell. However he does indeed part company with Treadwell as shown in Grizzly Man on the latter's view of nature and particularly wild, dangerous animals as essentially benign and our friends. You like Treadwell are taking a leap of faith when you say he crossed the line and lived among the bears. He came close to the line, but what indication is there that he actually crossed it? Have you interviewed any of the bears? He didn't live "among" them; he lived alongside them. This is an important distinction. Aren't you making a leap of faith here? The best that we can possibly say is that we don't know. But Herzog sees an alien otherness, a blankness in the faces of the bears. He was convinced that the friendliness and kinship that Treadwell saw were purely his imagination.
