The Goering Problem
One thing that is really misleading about this movie is its portrayal of Hermann Goering as buffoon. This license can be justified as the point of view of the movie's Hitler blaming everyone but himself for his failure and considering them to be fools, buffoons, traitors etc. It would be a mistake to confuse this image with the real Goering, a very savvy criminal even if a poor(*) military strategist driven by vanity rather than reality. In particular he said something during the Nuremberg trials that is a warning of lasting value and clearly understood by the neoconservative clique that makes policy for the GW Bush administration:
"Of course the people don't want war. But after all, it's the leaders of the country who determine the policy, and it's always a simple matter to drag the people along whether it's a democracy, a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked, and denounce the pacifists for lack of patriotism, and exposing the country to greater danger."

(*) he consistently overestimated the capacity of the Luftwaffe to accomplish military objectives. The non-Nazi world can be grateful for that and Hitler's errors of judgement (for example, invading the USSR when he might have just effectively annexed Romanian oil from a cowardly Stalin and declaring war on the US after Pearl Harbor sealing his fate by opposing another great power on a second front), otherwise Nazi Germany might well have consolidated western europe for very long time and turned it into a death camp opposed by only Britain as Stalin did the same in the USSR. Thanks to Goering, the troops escaped at Dunkirk the Luftwaffe being unable to singlehandely annihilate them, the battle of Britain was lost due to the shift to bombing civilian targets instead of destroying the RAF in preparation for an invasion, and Germany fell well short of promised results on the eastern front with disasterous consequences for Germany.
