Disney’s fairy franchise flitters on, weaning youngsters on indifferent product so they won’t feel so bad about future Star Wars sequels. This instalment is Valley-Girl Aesop, with the irritatingly diminutised Tink plucking a thorn from, and thereafter domesticating, a fearsome cat-creature. Though our heroine remains more self-reliant than most Disney princesses, the film is too mild to constitute any kind of statement; the animation’s blandly functional, while KT Tunstall’s songs fly straight between the ears. Better than last year’s pirate one, but it still feels like a short padded to feature length so that more of that sweet 3D surcharge can be extracted from parents’ pockets.
