In which way did leni riefenstahl's work influence current Documentaries?

I was privy to her propaganda documentary made especially for the Third Reich. The Nazi collaboration aside, I was struck by her explicitly beautiful stylization and poignant graphics. I am actually in awe of her talent as a movie actress turned director and producer. It is said that she was a pioneer in terms of new film aesthetics and camera angles. Does anyone know in which way she pioneered this and how is it seen and used today?
