Far outside what’s normally taught as “history”, this 6-hour documentary attempts to explain what’s normally glossed over – Germany’s actions prior to WWII, Hitler’s popularity, the support of the Nazis by the Germans, the basis for hardline Nazi stances against Jews, and why Nazism was such a danger to the established world powers. It chronicles the German WWI defeat, communist attempts to take over Germany; hyperinflation during the Weimar Republic, widespread unemployment and misery that served as the foundation of Nazi principles, and Hitler’s amazing rise to power. It also reveals a personal side of Hitler: his family background, his artwork and struggles, and what motivated him to pursue a career in politics. While open to criticism for being “pro-Nazi” in its perspectives, the documentary does present many factual foundations for those perspectives, highlighting an endless list of hypocrisies and double-standards imposed on Germany in the years before, during, and after WWII.
