I feel this need to voice an opinion on the movie, simply because of the recent hubbub on social media and in the blogosphere about the intended message(s) of the story. The way I see it is you see what you are looking for in any movie you watch or song you listen to or picture you scrutinize. If you are looking for something horrifyingly inappropriate, it's going to be there. But if you are looking for something beautiful and positive, you are just as likely to find it, especially in a movie made for children. (See the very end if this post. And every post in this project.)
That being said, the overall messages I took from the storyline of Frozen are twofold: First, you have to believe in yourself and your abilities, otherwise personal growth is almost impossible. Know your limitations, but don't let them hold you back.
Second, relying on your family is of the utmost importance, especially your sisters!
Which is why I intend to give Littlest Sister her own copy for her birthday. I'm pretty sure she won't comprehend these ideas just yet; to her, Frozen is a really awesome movie with pretty princesses and a funny snowman and lots of memorable music. But someday she'll understand why I believe so strongly in the moral of the story.
