If anyone wants to watch a highly oversimplified Germano-centric and, from my other reading, somewhat inaccurate documentary of the first part of the Second World War, I can grudgingly recommend the Lamancha Productions “Visions of War” series, Galaxy Film 1983 presentation of “Blitzkrieg” by Karl Ullman, directed by Wolfgang Richter.
On the other hand if you want to view some excellent archive footage of the same period I can heartily recommend the same film without the soundtrack.
In its defence I would say that it is good to see anything from the other side of the hill.
General Whiskers' semi-historical wanderings 
With a title like that, I’m hooked 🙂
