I am the guy who thinks Science Fiction should have science with it, not just flimsy background for a big bada-boom. You must be the other guy.
The Martian has been described as "a love letter to science", and I loved how it paid attention to details, because getting the details wrong is dangerous when your margin of survival is thin. I loved how Watney paid a big price when he got the details wrong.
I liked Star Wars and Star Trek as much as the next guy (the earlier ones more than the later ones), but I LOVED the Martian. Crichton was scientific on the outside, but internally never let the facts get in the way of the story he wanted to tell. In "The Martian", Weir let the details write the story, and just made sure it was an interesting story.
