Just a technological accomplishment for IMAX and 3D from Cameron, this time

Rating: 4/10 (22 December 2009)

but story-wise,this movie has gotten all its' Oscars in 1991, when "Dances with Wolves" was in competition. I'd say James Cameron wanted to reinvent 3D cinema, and not cinema, as it's been stated so many times. In this aspect, Cameron delivered, indeed. The 3D landscapes and rides on top of dragon-like birds are the strong points of this movie.
But is there any chance that this will become a classic ? I don't think so. This movie has more clichés than a crime-mystery book of the '50ies. If you saw "Dances with Wolves", or "The Last Samurai", then you know already everything this movie wants to tell you.
Visually, you can see remnants from "The Abyss", warfare machinery from "Matrix Revolutions" and in what acting is concerned, the only two performances that caught my attention were those of Stephen Lang (colonel Miles Quaritch) and Zoe Seldana (the CG character of Neytiri). Disappointingly flat performance from Sigourney Weaver (can't help to mention that she had the only "avatar" that actually looked like her). About Sam Worthington, if you saw him in "Terminator Salvation", you will notice that he only made it from supporting role there, to leading role here. Same-o, same-o.
So my advice is, go see it only if you have a 3D cinema near you.
