Another hearty note of approval here. I recall the first Spoiler point above making sense to me at the time, but it's now too long since my viewing for me to recall why. And I didn't know enough to be bothered by the second one. My own point of irritation was the script giving her a dead child; it seemed a cheap short-cut to Depth and Stakes and Recovering the WIll To Survive. And one blogger liked everything except her "thank you" at the very end. So we all have our points that bugged us, but nevertheless it's quite an achievement. It captures some of that feel of being in an environment very far from anything comforting or familiar or suited to our survival. I was lucky to catch it in 3D IMAX but it would be effective in any screening, I think -- but preferably in a theater, I'd guess, rather than at home.
