I'm not sure I think Ridley Scott deserves an Oscar for the Martian particularly. Or Matt Damon for that matter. I enjoyed the film well enough (though I thought Sean wasted in it: he seemed barely to be acting at all) - but I think any honours should go to the cinematographer.
I agree about the cinematographer. While I do not think Sean was completely "wasted" in it, he is always deserving of more screen time.
I am glad Matt Damon got a nomination. I don't think he should win, but he was required to act alone, none of his cast mates were with him. I can't even begin to imagine how difficult that was. Tom Hanks had to do the same thing in the movie,"Castaway". He also was nominated but didn't win. I look at this as a sign of respect from his fellow actors.
I think Sir Ridley Scott completely deserves his nomination and I really hope he wins also. If he wins, it would be because the Oscar Academy is finally acknowledging his body of work, not just this one movie. But, also his directing in this movie is simply brilliant also. He took a script which could have very easily been made to resemble any other sci fi piece of action/special effects fluff and really brought out the heart of an extremely human story. Instead of going for the 12- 21 age group of boys, he made this movie appeal to all. I think that is very Oscar worthy just in itself.
