German propaganda films made during WW2 and ordered by Dr Goebbels are not no easy to purchase, and find one of them is already a victory. No matter the message. After all, we have seen British, American - not French because France was occupied by Nazis then - so why not seeing a German propaganda film after all? We may watch this one as a documentary, despite the anti British accents and unrealistic behavior of the men aboard the sub; nothing to do with DAS BOOT atmosphere. Here they seem to have much fun and also enjoy enough comfort, compared to Wolfgang Petersen's masterpiece. It remains a must see for me. Forget the Nazi message, you are grown enough to appreciate at its fair level.
