So after a bit of talk about it on here, I watched this last night.
An excellent documentary, if a bit voyeuristic in parts. It was interesting to see how Treadwell fell into his bear life and the way Herzog fed information about Treadwell's life.
Though I couldn't quite see the link between not getting the barman role in Cheers (Woody Harleson got it) and suicide by bear.
Also, some of the people who were interviewed in the doc were hamming it up a little, especially the coroner.
