Yea, the visuals are awe inspiring. The story is...uninspired.
And yea, walked out "Dances with wolves IN SPACE" (think PIGS IN SPACE Voice) , having never watched all of Pocahontas I could only compare with what I knew lol.
P.s. Rakku Cameron never did Alien. He only ever did Aliens (Alien II). Alien I was Ridley Scott (Of Labryinth, Gladiator, and now Robin Hood fame).
As for me - I'm waiting for enough money to upgrade with 2nd or 3rd gen 3D TV/Blue Ray/glasses and THEN I'll buy Avatar....
