Moana (Carvalho) is a plucky Polynesian girl who revives the voyaging tradition of her island tribe, with the help of buffoonish demigod Maui (Johnson, exuberantly sending himself up.) The unabashed positivity is pure Disney but Bush's zingy screenplay satirises the studio's princess obsession and there's a refreshing lack of a love interest. A spirited, vividly realised and genuinely rousing adventure.
