I do agree.
Technically, it is very beautiful. Linguistically, it is very interesting.
Yet it was totally previsible and they used a lot of stereotypes (bad army - neutral/good scientists - nice natives). The movie would have been more interesting if it hasn't been so manichean and biased ("oh bad humans you do not respect your planet unlike them go to hell").
I am somewhat tired of all those plots revolving around ecology, it is true that we have threatened our planet, yet :
1- Making a movie will not save it, it's only encouraging people to use their car to go to a movie theatre made of any kind of polluting materials to eat junk food which most people have no desire to know how it was made and then to go to the stores to buy a dvd or a blue ray and a new tv (also made of polluting materials) to watch it again and denounce the attitude of human beings in front of your screen.
No really, it's not hypocritical at all.
2- We do not know how an alien population would have evolve, which make the plot both believable and not believable. Observing the behaviour of human beings or animals on Earth, we could guess that there would be some wars between different tribes of natives (I assume they are tribes since they was such a huge gap between our technology and their) and that there would eventually be some tribes which would have tried to create more powerful weapons (I am not talking about our moderns weapons).
3- The deity was somewhat unrealistic in the end but I enjoyed teh fact that they justified it scientifically, yet it seems that most people took it as a moral lesson, meaning that we have forgotten how to respect and adore Earth and its soul (I do not believe Earth has a soul, I believe that we are making its inhabitants die but Earth cannot care about that).
Plus, we cannot go backward, how many of us could live without technology ? (I could not, I would not even been there since I am a premature child)
4- The body were idealisitc (no visible difference between the way individuals were built) but somewhat realistic according to the way they lived, nature was glorified but proven dangerous as well, I think it's too bad that they glorified it so much that no one saw the flaws in the na'vi attitude. It is true that creating eleves-like creatures without technology tend to make people think "how they are nice", plus they respected their planet yet... they accepted SOME humans and let everyone else die, they did not give them another chance and acted just as bad as human did, it was a real conflict were both part had there flaws but most people will never see it because the na'vi have been glorified for their way of living.
By the way, the movie was totally previsible because it used so many stereotypes and a unoriginal pattern (many movies do that but this one has also the pretention of being the best movie ever made) :
1- Army = Bad dumb people acting like tyrant
2- Scientists = Good people who have to work with bad army and whose intentions are misunderstood
3- Natives = Good and peaceful people who are threatened by a technologically advanced population
It is totally manichean, in reality, there may be people who threatens other but in the end, it is not "good vs bad", many things happens and the "nice people" my have threaten other people before too. It's the way things are, humans are animals, they don't really fight for a territory but they fight for a kind of spiritual / political /economical territory. I do not see why natives would be different, even natives of another planet (especially since the animals have a realistic behaviour and since the na'vi are domesticating them like we did).
Plus, the plot, as is says before this post, is just like Pocahontas's plot and you could guess everything which happened if you had seen other movies before :
1- A man meet a woman and they fall in love though they are not supposed to (especially since they are from different specie and ennemies)
2- Whenever someone says that "no one has done this in ages", the hero will be able to do this.
3- The war was totally expected, had they come to a diplomatic agreement, it would have been original
4- The hero becoming his avatar... how unprevisible ! No one could have guessed from the start (especially since he had a handicap) !
No, really, I paid for this movie because my best friend wanted to see it, I am not disappointed because it was visually beautiful but I will not see it again because it would be boring.
