Although I disagree wholeheartedly with the content, the cinematography is a case study in propaganda filming. Lighting, angles, etc. are all used to create a sense of majesty even as people are being stripped of their rights, and so effectively so, that they clamored for more.
The same techniques are used by propagandists today, from TV news to Hollywood (and other) movies.
It is one of those films that you can only praise in the proper context as too many people will automatically jump to the conclusion that you're a nazi (Joe are you now or have you ever been a nazi?).
No. I have never been a nazi, and have no desire or inclination to be one.
As abhorrent as the nazis were they did leave items of historical significance. That film is one of them.
And those who do not learn the lessons of history are doomed to repeat them. I am afraid we have reached the point where segments of our society are susceptible to that sort of programming, regardless of the 'message' behind it. Knowledge of and vigillance against those techniques is the best defense.
