I have a slight fascination with Adolf Hitler, only because I want to understand how such a evil man could come to power. I am convinced Hitler was a psychopath, or at least seriously mentally ill. I happened to see Roger Ebert's review of Triumph of the Will, the 1935 Nazi Party propaganda film, where he describes it as a terrible film, but historically significant. I started watching Triumph of the Will on YouTube, and the first ten minutes I thought was fascinating. Hitler in these scenes is almost comical, since he seems to struggle to keep his armed raised through a vast parade, and his slight plumpness makes him look clownish as he smiles at his success. In these scenes it is hard to take him seriously.
I found the first 50 minutes to be pretty interesting from a historical perspective, but the last 50 minutes is almost nothing but repetitious marching and parading.
From the video I think I understand better how such an evil man can come to power. About 25 minutes into the video, the Reich Party Congress promises people the world.
