I don’t understand why it is PG, but this is an amazing movie otherwise! I was on the edge of my seat the whole time! I think kids 9+ would enjoy it, but it might bore kids under that age. I think that the main sailor, Tracy is such an inspiration to young girls all around the world! And I think that it’s a lesson telling them that they can do what they want, even if someone tells you you can’t do it. This is a great lesson, especially with the discrimination that’s going around these days.
