It’s hard to believe Matthew O'Callaghan hadn’t directed many films before this one—just three TV specials—because he really knocked it out of the park with this movie. Everyone involved, from the actors and writers to the animators and director, did an exceptional job. The animation itself is vibrant and full of feeling; it’s just outstanding. I'm not exaggerating when I say that this is without a doubt the best film I have ever experienced. If you subscribe to Hulu, Peacock, or the Disney+ and Hulu package, you really should give this a try—it’s absolutely worth your time.
