Steve , I am waiting for your remarks
okay. Ah-hem.. Let's see, where do I start. 
I'm not a great fan of the stories on Hitler and especially his last days. I am interested to know more about the political deals he made while rising to power but by the time April 1945 arrived Hitler was totally out of balance. This movie does protray this in ways that I have not read or seen. It shows the German commanders still under Hitler's influence and holding out some hope of a turn-around, that is until, they get news that the other armies are surrounded and may surrender. Then the staff begins to turn against Hitler.
It shows his reaction to Himmler's letter to the Allies with an offer of surrender. Then at the end of the movie, it shows the Russians turning down the German commander's request to negotiate a surrender----accepting only total unconditional surrender.
The story details the last days and the deaths of Hitler, Speer, and many of those inside the Bunker. You see the events from the secretary of Hitler and one young Nazi youth fighters, as well as a couple of other individuals who survived the Downfall.
As with most sub-titles, this was a distraction. In one scene where the narrator was reading a letter or talking about one thing and the action was showing another, I had to re-wind it to watch the action and then read the subtitles.
About the R-rating; it did have some violence and some nudity. I would not judge the violence that bad---not as bad as "Schindler's List" or "Saving Private Ryan". ((I had sworn not to see the movie "Munich" because of reviews about its violence but finally watched it and it wasn't what I was expecting.)) And the nudity a couple of topless scenes and one of those scenes was minimized---at least in my version I was watching.
The acting was great. The shots and scenes looked as real as could be.
Well, how is that? If I get bored around here on Memorial Day off, I might watch it again and give more comments. But there is already a lot of War Flicks on the Tele.
