Although long, tedious, and Hitler sucks, the film is worth it in terms of the technical aspects of film making. Leni Riefenstahl did a good job.
The highlight of this documentary was the Sieg Heils. Besides the funny, awkward march of the SA and SS men, workers, and children and Hitler’s tantrum-like speech at the end, every German at that time parading the ridiculous salute (right arm diagonally raised and suspended forward) was like a one-arm-raised zombie.
