This film is about 2 things, as I see it: space-station missions and survival. I think the movie accomplished an interesting story in both respects. As to the latter, the film did a good job of establishing a desperate pace, in which: every second counts; there is little rest for the weary, and Murphy's Law is in full effect; and no one is going to save you but yourself, so you better nut up or shut upfor good. Space is a perfect setting for these themes, as the movie effectively conveyed the isolation of space, the importance of rigorous training so ingrained that certain actions become involuntary, and the sheer wonder of modern technology. These aspects of the film, along with its breathtaking scenery and its compelling acting (by the way, props to Bullock for her hard work on that rocking 49-year-old body!), almost make it a Must See; but overall, my reaction to a friend who tells me that he hasn't seen this flick will probably be more like "It's worth it if you ever do, and see it in 3-D, if you can" than "You really need to see that movie."
