Frozen.
It’s not my favorite Disney film. At all. It has its moments, but the plot begs for more backstory and explanation of early story contrivances regarding the Elsa character; the movie’s message of female empowerment does not speak to me personally; and the true villain of the story turns out to be rather ineffectual, and not in an amusing or comical way. The film is not actually about the villain at all, who is really more of a side character to the plot.
The thing that bothers me about Frozen doesn’t even have anything to do with the movie itself, it was the movie’s damn ubiquity. I don’t have a problem with merchandising, but sometimes it gets to the point where it’s just too much, and I think that happened with Frozen. It came out in 2014 and I still see commercials for Frozen toys. See also: Minions.
