Frozen" is a story of two journeys: one of Princess Anna, who wants to rescue her kingdom from a permanent winter, and the other of her older sister Elsa, who (unintentionally) generated the blizzard that has entrapped their castle and its surroundings in mile-high dunes of snow.
And actually, "Frozen" also marks a journey for Disney, which took some risks in bringing a complex but honest message about women and sisters, love and identity to an audience used to splashier fare from the company. "Frozen" turned out to bag two Oscars (best animated feature and best original song), in a triumphant victory over Hayao Miyazaki's swan song "Kaze Tachinu (The Wind Rises)."
There was some criticism in the U.S. that Miyazaki's work smacked of nationalism, placing the golden statue beyond its reach. Still, "Frozen" shares a similar spirit to much of Miyazaki's work, with the message that a human being, regardless of gender, age or circumstance, must come to terms with their own identity in order to love and serve others.
