There's the surly Kristoff (Jonathan Groff), who aids Anna on her quest; Prince Hans (Santina Fontana), for whom Anna falls at Elsa's coronation; and Olaf (Josh Gad), a seemingly totally incongruous sentient snowman that should have been a swing-and-miss and somehow ends up being a delightful, hilarious home run. Directors Chris Buck and Jennifer Lee (both awarded 'Story by' credits along with Shane Morris, with Lee given sole credit as a writer) rarely go in for flashy 'camera' moves (is it still conceivably a camera movement if the film was in fact made entirely with a computer?), but nevertheless display a real knack for visual storytelling. This is particularly true of several of Frozen's barnstorming chase sequences.
Early musical number Do You Want to Build a Snowman? condenses the sisters' journey from childhood to adolescence and then adulthood via a tragic event that really stings. It's not over-praise to liken this sequence to the great opening montage of Pixar's Up (2009). While not all of the film maintains this level of brilliance, Frozen is consistently fun, and often very moving. Aside from the film's signature tune Let It Go, the aforementioned Snowman, and Olaf's song In Summer, most of the musical numbers are merely decent, and there none at all in the final thirty minutes. That doesn't prevent Frozen from being a charming, sincere animated adventure with a warmth that should melt the iciest of hearts.
