IMO one of the more realistic or at least convincing survival shows:
A man and a woman are sent in from episode to episode changing types of wilderness with ONLY one chosen item per person and a camera team (officially they do not intervene). The two strangers have to survive and travel to an extraction point in 21 days.

Often survivors in TV Shows don't really suffer or only a bit. This show however, like I said is more realistic and convincing, because you see the candidates hurt: suffering emotionally and physically. This is what I believe survival is more like. Of course they know that they will be saved in live threatening situations and get out after 21 days, but the lack of water and food etc. has to have these consequences like emotional breakdowns, lack of motivation and so on. This is what the show focuses on.

It's too bad that the show is often cut like an entertainment show. When the show simply skipped a few days, I often asked myself: "Haven't they done something noteworthy in the last days?" But therefore they show more or less irrelevant interviews. In the episodes with bonus material you can sometimes see what happened in the remaining days. This should be in the main episodes is the first place. The interviews are secondary for me.

Would be great if they also focused or will focus more on the survival techniques than only the suffering of the candidates.

All in all: Good concept with lots of potential!

Btw: often they use marvelous nature fast motion and wildlife fillers.
