Hmmm ... I saw it too, and I confess I didn't really like it; neither did the half-dozen or so friends I saw it with. (Of course, we're all sarcastic twenty-something physics majors, so I'm not sure we're a fair sample.) I have a number of Russian friends so I was bothered by the actors' carelessness with the accents - it would have been fine if everyone had a Russian accent or if no one did, but the weird mixture didn't really work IMO. My friends and I thought most of the characters were really caricatures. Harrison Ford married well and had a dad in the gulag and don't take nothing from nobody. Liam Neeson loves his men. Anatoly is religious, but icons are forbidden. Rozhenko is young, inexperienced and has a pretty girlfriend. That one other guy has a pet mouse, and another guy is a chef, and one of the reactor crew is blond. When no one is sketched out any better than that, how are we supposed to be affected by their sacrifice? The poignancy of the movie is supposed to come from real men, faced with a tough decision, who freely choose to die horribly in order to save their ship and their shipmates. The "real men" in this movie are cartoon characters.
I'm glad y'all enjoyed it though.

The above is just the opinion of my little group here in East Lansing - of course everyone has different tastes.
