As I sat with my 7-year-old daughter and her friends in a movie theater for a showing of “Frozen II,” I was fascinated. No, it wasn’t with the autumn scenery, or Olaf’s comedic retelling of the first Frozen, or of Elsa and Anna’s acts of heroism during the climax of the film. Instead, I was highly satisfied with the way they portrayed the indigenous tribe of the Northuldra and their relations with the mostly white leaders of Arendelle. Spoiler Alert.
