Perhaps as fascinating as it is terrifying, this trilogy of documentaries are best watched together in order (vol. 1 "The Enigma of the Swastika" vol. 2 "The SS Blood and Soil" vol. 3 "Adolph Hitler").
Each volume focuses on a different aspect of the Nazi ideology, and the influences of the occult, mysticism, ancient Nordic religion, Germanic mythos, and racist theories of a superior Aryan man on the system of politics and belief that was to turn Germany into one of the most horrific forces of destruction and brutality in recent history.
There is perhaps no limit to the amount of discussion that can be had over the shocking actions of the Nazis in the 1930's and 40's, and so this series can only begin to scratch the surface. Yet, it seeks to try to understand the ideology that existed prior to Hitler's rise to power that was fostered and developed in order to achieve the ends of power-hungry and blood-thirsty men.
The DVD edition (1998) comes as a boxed set of three discs, each containing under an hour of video with narration (a bit over two and a half hours total). The extras include posters, trivia games and other nice extras typical of Madacy's bargain disc sets.
Overall, a thought-provoking commentary on Hitler and the Nazis, highly recommended for the student of history, politics, or religion.
