I never believed that such a documentary series could be so misleading and inaccurate. From the 1st episode, the narrative of an invasion of Italy in Greece (and the use of a map which shows weak Greek resistance) proves that the documentary has no accuracy and historical relevance.
In reality the Italian invasion in Greece failed and it was the first message to the Axis that Allies are resisting. The Italians encountered unexpectedly tenacious resistance by the Hellenic Army which stopped the Italian invasion by mid-November 1940 and pushed back the Italians back into Albania. As a result, Hitler decided on 6th of April 1941 to invade Greece (Operation Marita).
This huge mistake proves that they didn't have historical background check.
