Titanic director James Cameron doesn't make many films, so when he spends ten years and 200 million dollars on an epic sci-fi flick designed to revolutionise 3D cinema, you have to pay attention.

And that's exactly what the Internet has done, following every rumour, hazy image and tidbit of information with rabid fervour.

Actual footage of the film, however, has remained frustratingly hard to find... Well now the trailer has been released, and it turns out there's a reason for its previous absence. To be blunt, this film looks rubbish -- a mess of CGI, blue Jar-Jar Binks lookalikes and risible sci-fi dialogue.
