I read this book 3 times, my wife never read it. I was interested in seeing the movie adaptation but a little worried that it would spoil the story (as movie adaptations often do) but quite the contrary, this was actually a very well done adaptation. Both my wife and I thoroughly enjoyed it (she would rate it higher -I only gave it an 8 because of certain things I'd hope would be included, were not (no spoilers here.) -Let me say that the book was a bit overly detailed in areas to explain situations, but the movie did an excellent job of getting around it -is very entertaining and didn't have any "dull" spots. The movie is set in "near future" which makes it pretty easy to buy into the science and ideas (a nice change for a sci-fi movie). I will purchase this when it comes available on blu-ray. Matt Damon was perfectly cast as Mark Watney -clearly, he was a fan of the book (just going by the excellent portrayal). Its definitely worth the view. Probably my favorite this year.
