A review of the Olaf movie:

Collider "Once Upon a Snowman" is very much worth seeing. This gorgeous animation, completed at the end of the "Frozen 2" production, is gently sweet and explores the unknowns of the franchise's mythology with humor and sophistication, reminding us why we fell in love with the film in the first place.

ComicBookMovie.com: Unlike many of Disney's and Pixar's shorts, "Once Upon a Snowman" has nothing that will stick with you long after you've seen it. It is an enjoyable and heartwarming experience, no doubt, but it is also somewhat simplistic."

Where the Laughs Come From: "The family-friendly style provides laugh after laugh, while at the same time reaffirming the family love theme of the original film."
