In space, no one can hear you kvetch.

For lovers of the book: Almost everything is here though some of Watney’s funniest asides have been cut for running time. However, this being a movie, Damon is able to sell some of the comic commentary just by looking at the camera, something not possible in the book. A great feel-good film with a surprising bit of emotion in the climax. A few extra crises Watney faced are cut from the book, but understandable given the film’s over 2-hour running time. It’s well worth the ticket price and the 3D really adds to the beauty of the Martian vistas. A+ for getting people interested in space again.
