I read The Martian before seeing the movie. There were actually a few major events that were not even mentioned in the movie. The movie was still excellent, but as per usual the book is clearly better. And I saw the new Bond movie the other night as well. I'm a huge Bond fan, and I liked it. Not nearly as good as the last one, but still pretty solid. But parts of it were pretty slow, so I suspect some may not like it so much.
