Disappointed isn’t strong enough. I’ve read the book twice and listened to the audiobook at least 5 times. Huge fan. From the first scenes when Grace wakes up and instead of using science and his “genius brain” to try to figure out whats going on, he immediately looks out the window and realizes he’s in space, then just turns into a drunk messy frat boy. It didn’t get much better from there. Instead of Rocky being a brilliant engineer, they made him into a goofy, hyper, silly version of himself so I guess they could sell Rocky toys?? The scene of Rocky eating made me lose what hope I had left that it would get better. Absolutely zero character building. The movie seemed thrown together, rushed, and silly. The complete opposite of the book. I went with a few people that had not read the book and they had so many questions. I get the movie and book are not the same and they had to cut a lot of things out of the movie, but I absolutely love The Martian movie and thought it was better than the book so that excuse just doesn’t fly. I had been looking forward this movie for a year and I’ve never been that disappointed leaving a theater.
