Der Untergang is an amazing film?

I just got done watching th movie "Der Untergang" (Downfall). I was just captivated by the movie it was such a emotional rollecoaster. Since the film is from the german perspective it was quite interesting to see how the third reich was collapsing minute by minute. Bruno Gaz not only played the part of Hitler dead on. He embodied the character. I felt like I was watching the real thing. The movie had so much suspense with people blowing their brains out every couple of minutes it was intense. I was feeling not sorry for Hitler but sorry for all those who were fighting a lost battle believing in their furher. I was saddened to see people being killed while Hitler was just hiding in his bunker like a scared little bunny. I really enjoyed the gradual decline of Hitler's sanity he was moving invisible armies,and blaming everyone around him for his own stupidity. His mistress eva braun was played really well by Juliane Kohler. It amazes me how a man can call everyone around him cowards well he is the one hiding in a bunker. While what's left of his army and citizens are fighting a far superior force. Can anyone give me any more details of the battle of Berlin I would like to know more about the start of the battle and the end of it. : D
