The Martian in three acts

I saw a movie yesterday called The Martian, and in my opinion it had NO discernible second act. The conceit was an astronaut gets left on Mars and must survive, and I'm not sure much else happened. There were a couple of minor subplots that were part of the 2nd act: one had to do with an internal debate at NASA about whether to save the surviving astronaut, but it was minor, and another about the guilt/obligation of his fellow crew members to go back to save him, but again so minor you'd never for an instant say that's what "The Martian" was about. I think what would've made the movie interesting, or one for the ages, would be if the astronaut a) either didn't want to leave Mars, and had decided he could survive there, because of his disillusionment with the earth, or b) if he went crazy, and you weren't sure if he wanted to survive there, or die, or something like that. It would've made the movie psychologically interesting, rather than a very dull plot driven exercise, that looked good visually. Astronaut gets stuck on Mars, learns how to survive, contacts Houston, gets miraculously saved, the end.

I suppose the 2nd act is the psychological drama, that the conceit spurs on. I would've loved to see the astronaut fight NASA, either because he wanted to be left alone, or he learned that they left him there to die and was struggling with his disillusionment, and think that would've made it a truly interesting story, the meat of the conceit. The 1st and 3rd act would've been the same, he would've been left on Mars forced to survive (the conceit), and then he'd be saved (wrapping up the conceit), or not, but the middle of the story would be completely different. There really was no story to speak of, no relationship that the astronaut had either with aliens, the crew that ditched him, or mission control in Houston, just nothing to substantiate the conceit. I really seriously couldn't tell you what the movie was about save the bleedingly obvious that could be summed up in a word or two. Aside from artistic flourishes, the Martian was no more than a run of the mill police report, and those don't exist in three acts. They state the facts, and leave nothing to the imagination. It's the detective who looks for motives, or something interesting going on beneath a simple accounting of the facts, or the beginning and the end, that makes a story. You could almost say the second act is the internal detective work of a story.
