“Moana,” Disney’s breezy foray into Polynesian myth and culture, was released almost exactly eight years ago. Anyone remember what was going on that month? Amid an election, a reckoning and political anxiety, Moana’s anthems about voyaging beyond the confines of her coral reef (the tropical version of a glass ceiling) to save her people from environmental disaster rang out with special feeling.
That resonance doesn’t really carry over into “Moana 2,” a sequel that seems to abide by the “if it ain’t broke” rule. Directed by David G. Derrick Jr., Jason Hand and Dana Ledoux Miller, the movie charts a parallel course to its predecessor, following Moana (voiced by Auliʻi Cravalho) as she leaves home on an odyssey with her island’s future at stake. Along the way, she meets up with Maui (Dwayne Johnson), the burly, smug demigod still prone to jaunty jibes — he often calls Moana “Curly” — and corny metatextual commentary written, presumably, for the benefit of the millennial and Gen-X adults in the room.
Coming off a successful restoration of the hydrosphere’s ecological balance, Moana, now a practiced voyager, begins the sequel by expressing an upgraded objective: establish contact with inhabitants of nearby islands. Soon enough, she receives a vision from her ancestors on the very topic, encouraging her to take an arduous journey across the ocean. Upon her dad’s urging, Moana assembles a small and somewhat haphazard way-finding crew, including a crotchety agriculturalist (David Fane), an excitable marine engineer (Rose Matafeo) and a muscled communications expert (Hualalai Chung). This jumble of new faces often feels like a waste of screen space, especially when the ocean, a wonderful animistic motif, is perfectly capable of buoying Moana on her travels.
