Frozen 2 had a beautiful autumnal palette, but as a whole was entirely superfluous to requirements. The first Frozen has been wildly overrated, but I don't hate it. However the only "Let it go" involving an Elsa that has any real emotional resonance for me is the finale of Indiana Jones and the Last Crusade (ironically, the Elsa in question couldn't let it go, though the bit that moves me is the subsequent exchange between Harrison Ford and Sean Connery). :)
