Maybe so, maybe not. It's definitely innovative -- but Pandora still looks unreal, and the Na'vi still look like what they are, virtual people rather than real ones. I can't resist quoting again from one of the two Guardian reivews, that "obscure" major London newspaper, by Peter Bradshow:
After a run-up lasting 12 years, James Cameron has taken an almighty flying leap into the third dimension. His first new film for over a decade is in super-sleek new-tech 3D, and it is breathlessly reported to have taken the medium of cinema to the next level. And who knows? When Michelangelo completed his sculpture of David in 1504, he probably thought it made flat paintings look ever so slightly Betamax. Maybe he put a consoling arm round the shoulder of Sandro Botticelli as the two men looked ruefully at Primavera, and murmured caustically: "Little bit eight-track, isn't it darling? A touch Sinclair C5, a smidgen video top-loader – compared to, you know, sculpture?" That extra dimension makes the difference, and a recent village fete in Ilfracombe offered an absolute game-changer of a hoopla-stall in hi-def first-person interactive 3D – or 4D, come to think of it, if you count the time dimension.
In other words, today's amazing innovation is tomorrow's ho-hum passe' technology. All this is about 3D, which still feels to me like a quaint Fifties idea, with the cardboard glasses people used to make fun of decades ago. They're still basically the same glasses!

You like concluding with a Latin tag; I'll conclude with a French one:

Plus ca change, plus c'est la meme chose.
