First class. Long but enthralling. The 3D was spectacular(sorry) in that it emphasised the beauty of the imagined world. The principal character started as an average paralysed grunt given a new existance through transposition into an alien body 'grown' with genetic engineering. The story was a new twist on the Noble savage and a Gaia where the world, life and energy are all understood at last. You must see it in 3D IMAX.
