Why making historical TV series based on lies? The answer is simple: propaganda. The purpose of this short series is to make German viewers proud of their history and increase the feeling of national identity in the shade of horrible crimes committed by the whole Third Reich and create a picture of Nazi Germany as a pacifist nation. The scene of Polish partizans speaking incorrect Polish with broken accent (it seems that no Polish actor was willing to collaborate) antisemitic statements towards Jews and locking them back in a train full off ghetto survivors is yet another attempt of transferring blame about Holocaust to Poland, a policy Germany continues since 1950 when it began with term "Polish concentration camps", which is still actively in use today in German schools.

To sum up, this 3-part movie isn't neither entertaining, nor historical. There is no reason to watch it other than learn German propaganda.
