DVD: Avatar, For retail & rental (20th Century Fox)

The key to enjoying Avatar is to accept that it's a children's film – whatever its director might say.

As long as you think of it as having the same target audience as a Disney cartoon, you can stop worrying about the twee new-age aliens, the eco-preaching, and the by-the-numbers plotting, and you can relish the pleasures of zooming through the skies above a gorgeously realised jungle planet. It's a wholesome adventure that's crying out for some Tim Rice numbers.
