The premise of this movie is so simple: An astronaut (Matt Damon) is trapped on Mars. How can he survive and/or escape? After a strong opening that set the scene right away, he combats the despair of being abandoned and the incredibly high probabilty of various horrible deaths with... humor. It's awesome. There's no weepy Tom Hanks Cast Away here!
It's good to be him. :P
This movie kept me very entertained and definitely wide awake and for a plot about a guy stuck on Mars there are certainly a lot of characters in this, each one with memorable enough quirks which actually strengthens it. I don't think there's any particular "bad guy" in this movie, just bad luck, which is awesome and adds to the whole feel good thing it has going. I mean, at least you've got disco music right? :P
Definitely a good watch and one I wouldn't mind seeing again! I give it four potatoes out of five.
