The latest film from the team responsible for the fairly enjoyable Ice Age series and Rio, this 3D animated movie is an ecological fable largely aimed at kids and centres on the epic struggle in an American forest between the positive forces of life and the negative ones of decay. The good guys are led by the Leafmen, a band of diminutive warriors who carry swords and long bows, fly on the backs of happy birds and worship a queen. The bad guys are commanded by the evil and equally diminutive Mandrake, and they control a flock of ravens and a colony (or cloud) of bats. Observing it all from above are two humans – a dotty environmentalist and his cute teenage daughter. Basically, it's a passable combination of Bambi, The Borrowers and Avatar (which plays in my memory as an animated picture). A necessary touch of comedy is provided by a slug and snail, which sounds like the name of a pub you wouldn't feel like drinking in.
