Earlier quoted context omitted.
I liked a lot of the ideas in PHM. I found the protagonist insufferable throughout, though. Perhaps Weir was going for a more flawed character after Watney? (Never read Artemis, so I can't comment there.) I still think it's a good book, and well worth the read. But man did that character grate on my nerves.
Yes, I think he was going for someone less likable. Watney was almost too likable.
If Willem Dafoe was cast, it could seem different :)
