Bought it and watched yesterday... loved it. The humor that Damon used in the movie had me laughing out loud multiple times. I thought this was very realistic to how an actual astronaut on a trip to Mars would respond. I remember seeing a documentary about NASA selecting the actual people for the trip that is going to happen in our life time. All of the different personality traits required to actually be selected for this trip. He stayed calm, for the most part, after every set back, because if he didnt start trying to work the problem, hed be dead.
As far as gravity on the ship, in the scenes I watched, only part of the ship was spinning, thus only that pat of the ship would have had gravity. Obviously, this is also speculation as to they even do this, but fro what I have seen, that is the leading choice for dealing with gravity in space as of now.
I loved the growing of food on the planet, and although Im not thinking it would work as described, we will be trying that in the future. Remember that Earth did not have a livable atmosphere long ago. So essentially the fantasy is to speed up the process on Mars and create an earth like atmosphere in the future.So why not!!
There was a couple of scenes that I was clinching my fists with excitement in this movie. The sound effects were AMAZING, and this was the real first test for my system with multiple subs as I just added a second sub last week. This movie had great low frequencies that shook the couch and everything else in the room, which is exactly what you would expect to happen if a rocket was firing near you.
I thought Damon did an outstanding job, as always, which isnt an easy task when you are alone for much of it.
I watched this by myself, but hope to watch it again next weekend when the wife returns from working in Memphis. LOVED this movie.
