"Olympia" is a documentary with innovative film techniques, despite the fact that it's over 65 years old, it's easy to recognize the influence that "Olympia" had not only in the documentary genre, but in the movies and TV transmissions as well.
The opening scene could be considered as an art film scene because it has many camera angles, slow motion, beautiful photography and background music. After this scene, the narration of the 1936 Olympic Games begins, and it's impressive to see how many swastikas were at sight in the games, it's in flags and in the uniforms of the german athletes.
One might think that the athletes in 1936 were very inferior to the current athletes, but "Olympia" shows how great those athletes were, in most of the disciplines they look as impressive as the current athletes. The use of different camera speeds and angles, can make you feel very close to the athletes. You can see their effort and competitive spirit thanks to the excellent use of the cameras.
Definitely "Olympia" is one of the best documentaries ever made. Absolutely recommendable.
