it was telling the story including life and death of bear enthusiast Timothy Treadwell. This story was the close interaction between the grizzly bear and Treadwell. However, it was the tragedy that Treadwell and his girlfriend were eaten by the bear before 2003 and this footage as found after his death. This story and the film were very impressive for me since the beautiful scenery and the cinematography was the contradiction to the narrative tragedy. The scenes shot by the Treadwell was very beautiful even if I knew this sad story before I watched it, while after I watched it, I forgot the sad story behind. I was impressed and intrigued by the beautiful scenes. What I see is grand and what I hear is horror. Watching the movie, it can be found that the chaos and insanity went through the film and this engaged viewers the most complex aspect of the film. The whole story was very interesting and special and considering that a person will spend thirty years in filming the bear under the risk of being eaten. It was crazy how mad this could be. From my point of view, this story behind was the key reason why it could win the Oscar documentary.
