The Martian (No Spoilers)

Went to see it yesterday, and I pronounce it very satisfying.  A fun adventure rather like Swiss Family Robinson and Robinson Crusoe, updated for Mars.  At the very start of the film, our hero is left alone on Mars, and must survive until a rescue mission can be sent.  It was visually stunning, well written, and did not talk down to the audience.  Example: there are a couple references to Hohmann transfers with no explanation to the audience what that is.  But that's a standard piece of spacefaring technospeak, and one that I alone in that theater immediately understood, and it would have sounded forced to explain it.  Great fun, even if you have to listen to the commander's favoritre music, disco.
