First let me get rid of the subtitle debate. I've been watching foreign films for many years and prefer them to dubbing. Of course the subtitles must be well done and easy to read or they are more of a hindrance than a help. As for the movie, it was informative, emotional, and thought provoking. What a heavy burden anyone in a leadership position has when his/her decision can bring harm to the people the lead. Can't imagine making the decisions that led to the out come of this situation, the Normandy invasion, our Civil War, etc. Whether I agree with the decisions or not, I admire the stamina it takes to make them.
I have to give a word of kindness to the poor German envoy (much like the Japanese Consul at Pearl Harbor) that tried to get a deal that would save lives. I think he believed this would be the best option for Norway. I'm surprised he wasn't just shot for having failed at getting the king's signature on the agreement.
I agree with all of the positive comments about the acting, script and cinematography. They were all wonderful. We all need to know more about the smaller countries that were part of the war. There people deserve recognition and our gratitude for doing what they could.
