Frozen II is a journey from the comfort and joy of home into an alien and dangerous world. The danger centers on broken trust. Elsa (Idina Menzel) learns that she must resolve a betrayal that happened before she was born. In addition, the trust between the sisters is fragile. Anna (Kristen Bell) wants to help magical Elsa against the new dangers while Elsa wants to stride out on her own.
There is a legend about an enchanted forest that is the focus of the film. It has been walled off from the rest of the world with no way in or out. Elsa hears an ethereal voice and remembers a story from her childhood about the North country. To solve the mystery, Elsa explore the North with Anna, Olaf (Josh Gad) and Kristoff (Jonathan Groff).
Memory is an recurring theme in the movie. Elsa goes on a kind of vision quest to learn what a magical river knows about the past. To resolve that past requires Anna’s fortitude when she realizes what Arendelle might need to sacrifice. The friends come to accept the history of their family, even though it is sad and painful.
The classical four elements, Fire, Earth, Air and Water are important forces in the enchanted forest. They seem dangerous and hostile, but they are gradually tamed. To understand the mysterious forest requires perseverance from both Elsa and the rest of her friends. They find the truth and liberate the forest so that its people can become part of the greater world again.
From the outset, Frozen II lets the audience know that they don’t need to see the first Frozen to appreciate it. In the first scene you see that Elsa & Anna’s childhood had been revised. The movie doesn’t look back and it stands strong on the new foundation.
Often filmmakers strive to bring out a specific emotion at the close of their film. The producers try to close the story with an exclamation point instead of an ellipsis. Frozen II does that better than most by eliciting an emotion that is rare in films. In the coda, that feeling is reinforced with the joy and freedom that fills the new Arendelle with magic.
