Sure, some of the things on MvW are setups, and he does get help. They probably should have been more upfront about that from the start. But just because a few of the things are setups (obviously done to make a more interesting/exciting show) people seem to discount the credit of Bear Grylls almost entirely.
This man was in the British SAS trained in a bunch of stuff including survival and being a survival instructor, he was one of the youngest people to climb Mt. Everest (this being after he broke his back in a parachuting accident). He circumnavigated the UK on a jet-ski. Crossed the North Atlantic Arctic ocean on a small rigid inflatable boat. Flew a powered parachute over the Himalayas to raise charity money for children.
He has accomplished more in a few years than most of us will do in a lifetime. And I wouldn't hesitate to say the guy could hold his own in a survival situation. To say you hate him or he's a phony or fake? What have you done lately?
