I remember watching a show a little while ago about Mont Saint-Michel in Normandy and how crossing from the coast to the island claims several lives each year since there are pockets of "quicksand" and the tide comes in so fast. The thing is, it didn't look like the quicksand on mythbusters, but more like extremely thick mud.
I can't stand Bear Grylles, I find him very shock value. The one in Africa were within two minutes of the show starting he is drinking his own urine. He does things where only someone in the peak of physical health and a SAS background go do it. Do you ever watch Survivor man? I find his show a lot better. Plus... he is Canadian.
Funny thing is, when Les when in the Sahara he purposely said that drinking your own urine is not recommended!!!!
Bear is over the top. Who else would fly strapped to a parachute and a fan pack over Mt. Everest?
Bear is the show off show. Les is the "if I can do it, you can do it" kind of guy.
I mean, Bear, while he jumps in frozen Alpine ponds, drinks muck from one of a dead camel's stomachs, would eat camel spiders, climb down waterfalls...... he has a crew.
Les, while he doesn't eat camel spiders and drink his urine, he goes out to desolate places by himself and films himself for the 7 days (or unless they HAVE to get him, like what happened in Labrador).
So Les: authenticity value, guts, and can go it alone
So Bear: shock value. Doesn't go it alone, has a crew with him, what is his crew, we don't know what's going on when those cameras turn off. It's like an expensive home movie with Bear having unlimited cash to go to far flung places to act like a kid. Survival? Not really, showing off? Yup.
