when the young Canadian sailor was rescued and captured on the German warship, his p.o.w. status was the first time that i've seen in a war movie that a prisoner of war could be so easily walked around on board of the German warship and not be confined in the holding cabin under 24/7 watch. he seemed to be the only British sailor who's not wounded but still stayed with all the other wounded ones. he was escorted only by a German sailor to walk around having fresh air regularly in the day time. the way that a pow had been treated like a first class cruise ship was a shocking contrast to what we had seen in any WWII movie. then when the young sailor escaped, he chose to sneak off the ship without a shirt, and the shoes he wore were also quite convenient like a ballet dancer's, that's quite weird too. but the flaws i mentioned here are nothing if you've seen the whole movie, a great one!
