Well done adaptation of the book of the same title. I don't know why they felt it was necessary to add more to the ending than was in the book. It was unnecessary and reduced the impact of the film.

Great movie. Action packed and well thought out story line. Makes you feel as if you are there. A must see movie!

I loved it. From the visuals to the acting this movie was the whole package. It's surprisingly funny, tense when it needs to be, and Matt Damon killed it in the lead roll. I would definitely recommend this to someone, and also I'd say it's worth the 3D price too. It adds a layer of depth to the landscapes that make you feel lien you're on Mars.

Amazing! Had me on the edge of my seat!!
