A Mondo Italiano Little Mermaid that embraces its 20th century Mediterranean archetypes with a that’s-ah-spicy-meat-ah-ball fervor, it does not have the oversized imagination of an Inside Out, the end-of-innocence heft of the Toy Story films, or the pathos and wit of a Finding Nemo. It’s a much more modest affair, a tale of friendship that’s a very personal project for filmmaker Enrico Casarosa, yet one that’s capable of resembling a summer afternoon lounging by the shoreline.
