Never accuse James Cameron of being less than dedicated. The director who has twice created the biggest film of all time spent more than a decade waiting for technology to catch up with his ideas and developing cameras capable of capturing them. The results, however, were earth-shaking, Hollywood-changing and jaw-dropping. This isn't 3D-sploitation, with objects flying out of the screen towards the viewer. This is 3D as an immersive world, creating an entirely believable and utterly enchanting other planet to explore. As more and more films use 3D, this is the model they should be following.

Best Bit: The flying sequences, as Jake learns to manage his banshee and fly far above the Pandoran forest. But it's all great.
