The ending
Saw the movie yesterday and I loved it - great story, great actors, great all together. One thing that bothered me a little, was the ending (obviously: spoiler ahead)...
I really wanted to know what happened to Sgt. Rasmussen afterwards. To start with - how did he get the boys? Did he just take them away, blatantly disregarding orders from his superior? If that is the case, certainly there would be consequences. Would he get shot, disrespectfully discharged or what?
Also, looking at pictures on the IMDB page for Under Sandet events - I'm even more convinced of Roland Møller's marvellous acting ability, because with that hat he's wearing, I could not take him seriously (lack's any sense of authority...)
