I saw it in I-MAX 3D last night at Darling Harbour. Massive screen + giant glasses (a la dame edna) . I think the 3D experience is best viewed on a 16:9 ratio in a conventional theater. THe I-MAX screen is too big and you're forever looking up down sideways to follow the action. Was still a thrill though.

That was the third time I saw the movie so I started "looking around" a bit more. Has anybody notices that the human based Avatars have 5 digits on each hands and feet but the Na'vis have weird feet with only 4 fingers in each hands? Like the simpsons?
