I watched this because Kristi Yamaguchi was in it. I follow figure skating fairly closely and enjoy skating myself when my health permits.
I found the story entertaining and fulfilling, but the movie is full of inaccuracies as far as the world of figure skating goes at least as far as I have seen things myself. Although Tanya Harding's actions brought the world's attention to figure skating, she is an anomaly. Figure skaters do not generally try to hinder their competition, at least not so blatantly. Rather there is quite bit of camaraderie among skaters.
The national competition is a several-day event. Each skater must skate at least two programmes. This is done on different days. I'm not familiar with the schedules for school hockey, so I don't know when their championship would take place. The national skating championship typically takes place in January. They take place at a large public arena, not a small rink like the one used in the movie.
I was also somewhat incredulous that when the skater showed up all covered in paint someone didn't ask "What happened to you?"
Enjoy the movie but don't base your ideas about the world of figure skating on it.
