I watched the movie like 30 minutes ago, it was awesome indeedI recommend the book, especially if you're interested in how stuff works: Watney explains a lot of math and science with his dry humor (some people don't like that, but I was interested)I listened to the audiobook too, it's got a great narrator. Though it's harder to follow the math and ascii stuff (Like when Watney sends Earth the message "(. Y .)" for example) x)
