You know, a lot of it depends on your perspective.
I never saw his show as some kind of survival tutorial, and I don't think it's meant to be.
The title is "Man vs Wild", not Survivorman.
Let's face it, his show is about "I'm getting paid to f**k around in wild, exotic locations." It's an advanture show, not a survival show. I can't believe he'd take a lot of the risks he takes if he thought he was teaching survival. He's out having fun, filming it, and getting paid for it.
I daresay that more people probably tune in to Man vs Wild than do Survivorman. let's face it, MvW is more entertaining. I like both. Survivorman teaches me stuff, MvW stirs the enthusiasm of my youth. Heck, a long, long time ago, in a galaxy far, far away, I wanted to do the stuff Bear Grylls does -- I even thought that's what surviving was all about, lots of running, climbing and eating disgusting things. Now, I like to watch Survivorman so I can learn enough to NOT have to do what Bear Grylls does (OK, I learned more from Bushcraft b y Mors and a couple of Hood's Woods videos I bought, but Les is still good to watch.
So watch Bear for entertainment and watch Les for more reality.
