If you're looking for a survivalist show where people struggle to stay alive, this is not that. What it is, is a fun new way to do a cooking show where the contestants have to forage their own ingredients.
I do think that highlighting the survival aspect a bit more would be interesting but for a show trying to highlight foraging and cooking, it's accomplishing its goals. You do see chefs exhausted because they are getting minimal sleep, and affected by the lack of food or quality food.
If you are excited about new culinary experiences I would highly recommend this show. If you are looking for a show based on people surviving in the wilderness, this is not that. The cooking element is what makes this show fun, different, and exciting.
