Don't blame the sport too much.
IMO, the book that this movie is based on, "Little Girls in Pretty Boxes: The Making and Breaking of Elite Gymnasts and Figure Skaters" is too one-sided.
It's not the sport that's the problem. It's a handful of coaches and "stage parents" who put too much emphasis on winning instead of the gymnast's well-being.
Lately, however, the FIG, is making things more hard on everyone by making elite gymnastics more difficult and dangerous. Something has to be done with them. We should do what the girls in the movie Stick It did. Now if all the gymnasts would do that, the FIG would have to listen.
