I also thought that even though it was made for a Disney friendly audience it wasn't a whitewash of ballet. People in the documentary spoke frankly of the competition, the anxiety when it came to casting, the injuries, the financial strain put on families.
I also loved the respect between the NYCB dancers and the children in the Nutcracker. I loved Lauren Lovette telling the angels that she once faceplanted her variation and the angels were just left watching.
