This is one of the first Oscar nominated films I have seen so far this winter. Telling the tale of an astronaut isolated on Mars with only his wits to help him survive, it is thrilling, funny, uplifting and Matt Damon is excellent, carrying the film very much on his isolated shoulders.  With 3 of its 6 Oscar  nominations for sound and production design and visual effects it is also great to watch.  The science is mostly pretty good according the geeks who have seen it. Sure there are lots of misses and miscalculations to those who choose to pick at it but all forgivable in my opinion for an excellent cinematic ride.
