This odd little story is based on a book and, for an animated film aimed at pre-teen kids, seems unusually convoluted and protracted. But, as always with Japanese anime, it's visually a delight.

For almost all ages, this is a heart-warming, imagination-tickling joy - and a film that should put Ishida and Colorido on every anime fan's to-watch list.

The folks at Colorido would do well to ignore any such murmurs and simply create the kinds of films they want. With "Penguin Highway," they're on the right path.
