The movie is fine. Not Disney's most elegant storytelling, but hardly their worst. This is a beautiful movie about a family's love being strengthened by an adventure that shows them the beauty of their natural surroundings.
White conservatives are doing a lot mental gymnastics to say this movie is somehow awful or inappropriate when they're really just mad that this movie features positive depictions of characters and ideas that challenge their limited knowledge of the world. The film centers a happy interracial marriage, which makes them uncomfortable. The couple has an anxious teenage son with a crush on his neighbor, which seems like pretty familiar territory for a Disney film, right? Apparently because the son is gay, and the parents support him, this movie is now a political diatribe that no child will understand or should see. They do not consider that this movie is not only something that their kids can understand, but something valuable to kids who are black, or gay, or otherwise different. Yknow, kids that white conservatives dont care about. The film also depicts difficult relationships between parents and children, which I guess is shocking/ blasphemous to people who don't see their children as human beings.
Disney spitting this movie out with zero marketing is disappointing and cynical, but not surprising.
