Embarrasing to me as an American

I enjoy history. Stretching the truth is one thing but passing garbage off as history shouldn't be taken lightly. First off, the Polish were the first to get an Enigma machine. It was then handed off to British intelligence. Secondly, shortly thereafter another wheel was added to the machine once the Germans figured out the codes were being deciphered. Thirdly, the Germans were really portrayed badly here for no good reason except that a villain was needed. Though a submarine commanders job was to sink merchant ships I doubt a very high percentage were bloodthirsty killers of helpless people on lifeboats. That scene just wasn't needed. It added nothing to this movie. I just want to mention to people who say "its only a movie". That is correct. But after the producers were called out for the inaccuracies in the movie they added a disclaimer giving credit to the British in the closing credits. I like movies like The Great Escape, Cross of Iron where a more even handed approach is used. That all German soldiers weren't bad people. Just like men in the British or American armies. Men who wanted to be home with their families. Not on the eastern front or in the north Atlantic or North Africa etc...
