Not surprising. The shows are what, an hour? So with commercials, think of the actual footage we get to see of his adventures. What does he do the rest of the time? He has a camera crew/producers with him the whole time. Do you think those guys eat bugs? Do you think for half a second that when he can only find a tiny spot under the rocks for shelter, that they stayed there or had to go find their own? Do you think they are really even that far away from wherever those guys are staying? Do they only have a pocket knife and 1 match, too? Are they jumping into the freezing river and crawling down the face of cliffs with cameras in hand?
I have always figured that he has full access to food, water, shelter, equipment, clothing, lighters/matches, transportation, communication (cell phone and laptop), and other modern luxuries. It's a drama. It's entertainment. He's an actor. To his credit, he does a decent amount of physical activity, and we've all seen him eat some crazy shit. Some of what he shows us is interesting, useful, and good learning. But overall it's just television.
I mean come on, the dude is always upbeat and talkative. He almost has a gameshow host quality about him. Survivorman, now that dude is awesome. I totally buy the fact that he's on his own in remote areas. He's grumpy and less than articulate at least half the time. No smoke and mirrors, just a dude trying not to die for a week. No matter how much the guy from Man vs. Wild tries to stick to the survival routine, he is never really in any kind of real danger or even truly deprived of anything he needs.
