"Promise me you'll never forget me because if I thought you would I'd never leave," Christopher Robin famously tells his beloved Pooh, a bear with "very little brain", in A A Milne's heart-rending children's tale.
It's one of the saddest pleas in English literature. Here Milne's droll, melancholy adventures are given the syrupy Disney treatment. Pooh's Hundred Acre Wood gang – Tigger, Piglet, Roo, Kanga, Rabbit and the morose Eyeore – hunt down an elusive creature called the Backson. The hand-drawn animation is exquisite, the voiceovers are less so.
