There is a movie coming with Ryan Gosling, I sure hope they keep the spirit of the book and don't turn that into some bizarre hollywoodish cash grab

I think the Martian was adapted well from book to movie, so I have hope for this one. That said, compressing the entire story into a theatre runtime is tricky: I think it would be a win if only half of the character and relationship growth of the two ship bound protagonists comes through in the adaptation (because it was sooo good in the book!)
