The first time I watched it years ago, I remember feeling that I probably shouldn't have felt the way I did at the end. It's just such a powerful film, and it really gives you a sense of the long periods of sheer boredom, followed by terrifing periods where they could all be dead in seconds.
And get Stalingrad, you'll pick it up for buttons in HMV or the like.
Don't get the dubbed version, it's awful
