Since it is winter, what more fitting time is there to write about Frozen? If you belong to the group of people who just adore Frozen, I'm about to give you another reason to love it, but even if you are one of those people who think that this movie was kind of a flop on Disney's part, I ask that you consider what I have to say. You may be surprised.
At its heart, Frozen is simply about two lonely sisters who have erroneous ideas about love but gain a better understanding of it over the course of the story. This journey is what, in my opinion, makes it such a wonderful film.
Elsa's idea of love is constricted by fear, as she believes the best way to love her sister is by staying away, to protect Anna from the danger of her ice powers. Beyond being afraid of hurting Anna, Elsa is also terrified of what might happen if it became widely known that she has powers. She doesn't try to get to know Anna, and so doesn't actually know what her sister needs most of all—human interaction.
The whole "conceal, don't feel, don't let it show" thing is basically the driving force behind everything Elsa does. Thus, it affects her approach to love, and she even tries to push her parents away at one point, because she's afraid of hurting them.
Anna's idea of love, on the other hand, is very romanticized. We don't know much about how her parents were, but she was obviously very lonely, as she turned to paintings for company. Growing up in such isolated conditions, Anna had to come up with most of her ideas about love; namely, that finding romantic love would make her happy, and that "true love" could happen in an instant, if she met the right man.
We can see this in the song "For the First Time In Forever", as Anna sings about the opening of the castle for Elsa's coronation being the opportunity for her to find true love, thereby curing her of loneliness: "For the first time in forever, I'm getting what I'm dreaming of! A chance to change my lonely world, a chance to find true love!"
And she believes wholeheartedly in love at first sight because she acknowledges that she has one day to make this change. It is easy to understand, then, why Anna fell so quickly for Hans. He was charming, handsome—her dream come true!
So, we have two sisters who don't quite get the whole picture. What exactly changes, then, that makes Frozen such an incredible story?
In short, it's the definition of love that is made clear by the latter portion of the movie. Earlier, Olaf says that he likes to consider himself a love expert. And guess what? He's absolutely right, as he proves when he explains to Anna what love is: "Love is putting someone else’s needs before yours like you know how Kristoff brought you back here to Hans and left you forever."
And here we have a concrete definition of love, which also happens to be biblically sound. Right after an encouragement to be loving in Philippians 2:2, verses 3-4 show what that looks like: "Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of others."
And 1 Corinthians 13:5 says simply that love "...is not self-seeking..."
Nothing at all like Anna's dream of a fluffy, feel-good, attention-seeking love! One could argue that, by staying isolated to keep her family safe, Elsa practiced this kind of love, but she was actually motivated by fear; she never took others' needs into account.
Now, when Anna learns how to be cured of her magically frozen heart, she hasn't heard Olaf's wisdom yet. She has only heard from the trolls, who (although well-meaning) have suggested a "true love's kiss" as the act of true love to thaw her heart. Thus, she assumes that she needs to have Hans kiss her, since she believes he is her true love.
Anna doesn't get it. She is thinking about herself and her own needs and how she can hopefully get her life saved. We all know that Hans didn't really love her, but even if they had kissed, I'm not sure it would have saved her, since it would be coming out of selfish motives. Not an act of true love.
Finally, Olaf explains what love is, but Anna is still mistakenly thinking along the lines of needing a kiss to save her life. She's still focused on herself. And she also seems to be under the impression that someone else has to do this to her, not an free act of love springing from herself.
I also believed that when I first watched Frozen several years ago. I didn't understand that Anna was performing an act of true love by turning away from Kristoff and sacrificing herself for Elsa. When Anna froze completely, my young high-schooler self thought that Elsa's grief-stricken reaction was the act of true love.
It wasn't until much more recently (i.e. after I started college) that the true nature of that scene hit me. I had been thinking about it, and suddenly I was reminded of what Jesus said in John 15:13: "Greater love has no one than this: to lay down one's life for one's friends."
Anna stopped thinking about her own needs, and was willing to die to save her sister. She had to perform the act of true love to save herself, not anyone doing something to her. At the same time, for it to be an act of true love, Anna couldn't actually be considering her own needs as she did it.
And that, folks, is what Frozen got absolutely right. It is a story that is paints a beautifully accurate of picture of what love really is.
