This movie basically described perfectly that you can’t trust ppl for basic human survival. To put a secondary sexuality before the primary sexuality is absurd. How will the human race survive? Then on top of that in the last exercise nobody with survival skills were chosen. Nobody procreated, There were three secondary sexual beings a two ppl succumb to and illness and disease etc. it was a great plot of thinking outside the box in a what would you do moment. But critical thinking isn’t for everybody.
