It’s not often that I want to rate a children’s film based on its politics. But since The Box Trolls is a movie about a human boy who convinces a socially despised and persecuted group to fight back, a political consideration is in order. Visually, the movie is outstanding, if a little dark with its brown color palette. There is probably enough goofiness in the movie to amuse children, and there is a little bit of a love story with a message about the importance parenting and being yourself that should make it feel good. But it doesn’t succeed. Those messages end up looking like small curds when what we want is a big slice of cheese.
