Well, first of all they do state it very clearly, Les Stroud (survivorman) is alone. He carries all his gear with him sets up his own shots and is more than twice as hardcore as Bear Grylls (Man Vs Wild)
Les is a survivalist. Bear is well, a dumbass. Bear will put himself into dangerous situations that should not be atempted even by those in dire straights. I have seen him drop into a canyon he had no idea how to get out of. And he was recomending you do the same thing. Bear will say I'm going to show you how to survive if you accidentaly fall in the water. You first take off all your clothes and build a fire. Then you accidentaly fall in, get out, and go huddle by the fire and put on your dry clothes. Am I the only one that has a problem with this. You can notice when he is in copper canyon, he stands at the top of a gorge wondering how to get down. In the background you can see a nice easy switch back behind him. Bear will have his crew help him make rope, or shelter. He will not often spend the night out either. Youll notice in the morning he will ocasionaly have changed his clothes.
Bassicly Les is hardcore, and Bear is a bad influence.
