This is a really great movie. In some ways, it is my favorite of the year except Pixar's "Inside Out." I love the spirit of exploration and cooperation that it hints at. Its the kind of feeling that Tomorrowland tried for, but just didn't connect with. The movie managed to capture many of the meticulously researched details in the book without actually dragging the plot down. There was a villain in the form of the political head of NASA but they kept him fairly realistic. The argument of how many are saved is a very real one and by the pure numbers made sense.
The basic plot is about an astronaut that gets stranded on Mars without enough time to survive. The solutions that he thinks of are quite interesting and very realistic. It is also a gorgeous movie as well, well filmed and pretty to look at.
