The perfect e-ticket for a flight of fancy into a world far more gorgeous than our own. The film doesn't halve itself to appeal to two generations. At its best, it turns all moviegoers into innocent kids, slack-jawed with wonder.

The tireless volley of ideas and inventions make this a delight that should connect with kids and adults in both dubbed and original-language versions.
