I think it’s due to how knowledgeable, practical, and yet pessimistic Watney’s inner monologue is through the book. It’s one thing to see something go wrong on screen (they did show all of the major issues as far as I recall, and a few minor ones too), it’s another to have the main character scientifically dissect exactly how fucked he is or will be if the next attempt at a solution fails.
Nah. Derision, public shaming, and ostracism are fundamental to the maintenance of the social contract. How else can we moderate extremists? The denazification of Germany was effective because they didn’t shy away from these methods.
