If you're still interested, you can read my thoughts on the lyrics (the tune has its own issues) are below.
I'll set out the lyrics (centred) and my comments (left-aligned, below).
The song starts off pretty well. The scene is Elsa walking across a snowy mountain. There are in fact some footprints to be seen - hers (it's not snowing at the time). But we can forgive that kind of poetic licence: it is a pretty isolated location and there's no company for Elsa. More interestingly, Elsa really is a queen: people watching the film up to this point will know that she has fled her kingdom on her coronation day (for reasons we will come to below). So we are introduced to the idea that she has swapped being queen of a common or garden kingdom full of (warm) people and all their tedious concerns for a kingdom of isolation and snow. We can all see where that emotional development is going to go: she'll have to return to warmth and company. Good set-up.
The final line is delivered by Elsa directly to the camera with what one might call a pert expression. I can't recall another character in the film addressing us directly in this way. By doing it, she makes us her accomplices in her scheme of liberation, whatever it is - but then she turns away from us and a shiny snowflake-embossed door shuts in our face.
At this point I'm completely lost. It is not just that I have no idea what moral pre-teen girls are meant to draw from this: I have no idea what meaning they could extract from it. Is it about positively embracing your inner mean-girl-cum-supermodel and getting a palace out of it?
As I said above, this unclear, contradictory and in some parts just plain bad song is the heart of the film. By well before the end of the song, Elsa has achieved mastery over her curse/gift of making things frozen. She does not undergo any real further emotional development - the only thing the plot needs from her is for her to go back home and release her kingdom from the icy state she left it in. At the end she seems pretty happy to be queen of people again and to use her powers for good, but she doesn't have to change to get to that state (she makes the odd mistake on the way, but it's a little contrived). All the emotional (and actual) journeying is for her sister, who is much more like a real person.
So what are we to make of the song? Considering everything that it is wrong with it, it's not that bad really. I can only conclude that I should stop worrying about it. Let it go! Let it go!
