73.) The Martian [10/3/2015]

This was one of my favorite books this year, and when I heard that Matt Damon was cast to play Mark Watney, I was excited to see the movie; unfortunately, what I liked about the book (all the meticulous scientific description, his relationship with inanimate objects, etc.) just were not in the film; it did a good job of fleshing out Watney's personality, but the story was flattened out in exchange.
