2 and a half hours of tension with no breaks makes a tedious film. I'm surprised that all of the people remain largely emotionless during nearly every scene. There is no humor, no sadness, no hope, and surprisingly not even fear. This may be the first time Nolan has disappointed me, as it appears that he spent significantly more focus on the direction than on the script.

With all of that said, it is a supposedly accurate representation of the real event, and it is always beneficial to learn more about past wars.
