I thought this was a very good movie. For once we had a story showing the reactions of normal people in abnormal situations. Doing the jobs they were paid to do withuot the normal histrionics we see from movie makers when the topic is WAR. Welll acted, well produced and directed. No uber major actors involved. A very believable situation. The movie ended just at the right time, leaving the rest to your imagination, if you have one.
If you don't like this then you are probably more inclined to think the movie Battleship (2007) is a good one.
