Not quite a nature documentary

Watching the introduction to Grizzly Man, I was somewhat led to believe that the film would be more about bears than anything else. However, obviously the film is a far cry from a nature film. I thought it was especially interesting that they began the movie by explaining that the 'protagonist' was already dead.
I thought that a punctum of sorts was present throughout the movie. After knowing that the main character will eventually die, all of his foibles and ramblings took on a grotesque aspect. Normally, I would have found his demeanor just annoying, especially his delusions of grandeur, but in the context of the film these actions seemed more pungent.
Most interesting (and distressing) was the tape of his own death. What first struck me is that he would, while facing his own mortality in the face of a hungry bear, have the presence of mind to turn on the camera to film his own death. The tape itself seems to represent the height of guilty voyeurism. I so wanted to listen to the tape, yet at the same time did not want anything to do with it. The filmmaker heightened this anticipatory desire by showing himself listening to the tape on camera. I cannot think of many more types of media that are as emotionally powerful as that tape, created by a man in his death- with the lack of video footage creating even more desire and fear in its consumers.
