Just got back from The Martian. Excellent movie, I'd probably say it's my #1 of the year so far. There are some very interesting yet to come out, so we'll see where it eventually lands. But as of right now, #1 of 2015.
Hadn't seen any trailers or read/watched any reviews, so I knew nothing going in, which was wonderful. There were many things I liked about the movie, but the most stand out thing for me was how they made you care for Mark as a person, which is perhaps the most important part of a movie like this. He was smart, efficient, and determined, but he was also funny and optimistic, which made him very likable, and I thought Matt Damon did a great job playing all of that.
