Worse, a lot of the behavior on that show is terrible survival behavior. E.g. when they did the episode in Iceland Grylls at one point jumped into a water filled ravine to make it to the other bank, and planned to dry off in some geothermal area he could see in the distance.
Firstly there's no ravine like that in Iceland that you couldn't easily walk around in 5-10 minutes without getting yourself wet, and secondly jumping into freezing water in the wilderness and thinking you can dry yourself off in some unfamiliar geothermal area you can spot in the distance is beyond stupid.
Most of the world's geothermal areas (including Iceland's) are just a collection of steaming holes in the ground, or water either too hot or too cold to dry off in. It's much better to stay dry than to take such a chance.
There are examples like that in virtually every episodes. E.g. Grylls climbing down a waterfall that he could trivially have walked around.
