When I first got satellite tv (first time ever) earlier this year, I was fascinated by the show.
Then it was revealed (not by Bear himself, it was leaked somehow) that the stunts are staged and the accomplishments are faked. He spends the night in hotels some nights that the viewer is led to believe he spent sleeping fitfully in a hand-dug ice cave. It's kind of like watching a magic show on TV. In real life, you can't believe the magician just pulled a rabbit out of a hat, seeminly from nowhere. On TV, yeah, I've watched all sorts of staged, faked stuff on TV and that just doesn't impress me. I've completely lost interest in (and respect for) mr Grylls and his TV show.
Now, Les Stroud - he's the real deal. If he has to fall back and punt, he tells you so right on the show. Such as "It's getting too dangerous now, we have to call in the safety team" and they are totally up front with the viewer. They make a serious effort to keep such abberations to an absolute minimum. Everything he does is a real accomplishment and his deprivations on his excursions are real, and he does suffer from exposure and real hunger while out in the wilds "surviving". That man has my respect and admiration.
