To celebrate Earth Day, Disney+ released Polar Bear, the latest documentary from Disneynature, the studio behind Earth, Oceans, and Penguins. Like previous Disneynature documentaries, there is a light plot that drives the film, as we follow a mother polar bear preparing her cubs to venture out on their own in the world. But the main appeal here is getting to watch polar bears hang out for a couple of hours, while getting some quality narration from two-time Academy Award nominee Catherine Keener. It's like getting to take an Arctic vacation without having to leave your couch. If you are a fan of gorgeous nature documentaries, Polar Bear is just what you're looking for.
