Realising they were falling out of the animated movie game, the past few years has seen Disney really up their game. Instead of desperately trying to be hip and down with the kids, they've gone back to the roots of what made them so successful in the first place. Frozen is, thus far, the pinnacle of this new/old approach, boasting an updating of traditional Disney values (you can't marry a man you've just met). The standout element of the film were its songs. Simultaneously smart and subversive, they proved so potent that the soundtrack album went triple-platinum. Central to this was Let It Go, Elsa's ballad that sees her finally accept her ice powers, letting go (aha) of the parental-induced attempts to hide them from her subjects. Painfully catchy (good, because it was played on a loop for months after release), the song became an emblem of the movie, despite it working against what Frozen's actually trying to say. Let It Go is the unmasking of the repression put in motion in the prologue, but it's far from the overall moral of the film (it comes less than halfway through, after all). Elsa letting go of her inhibitions creates the whole endless winter issue and that lack of caring only makes things worse. It's only when she accepts her sister's love, understanding you can't just run from your troubles, that things really get back to normal. But don't tell that to the makers of the endless parody videos.
