Great for my older children. Good gymnastics throughout, and a clear indications of the level of discipline required. There is a little adult language and dealing with fallout in the main character's life after her mother's affair.
There was a large show of disrespect towards adults, but it wasn't left there. We learned why, and then the root of the issue was confronted and healed with the help of adults and friends, leading to great respect for her adult coach.
Younger children will have a hard time processing much of the film, because it is easy to only latch on to the rebellious parts, which are funny and "cool." I would recommend that you watch the film with your kids, because it leads to great conversations.
