Query: Good flick, slightly inaccurate historically

I hate to be picky..but the Enigma system was a stream cypher, NOT a code. A code encyphers the same item "battleship" say, in a finite number of ways. Eventually they repeat. The Enigma system would NOT repeat (in less than many years). That was it's strength. The movie publicises a little known, and scarcely appreciated part of WW2. Perhaps a major reason why we are not speaking German now. In my opinion: well written, convincingly acted, somewhat unkind to the Poles (who provided invaluable help to the Allies with their cryptographic skills - and were shabbily treated as a reward), but well worth a look. More historically accurate material is available from the Bletchley Park site for those interested in persuing cryptanalysis more deeply. Cheers..
