If you read you can find spoilers, so if you have not seen the film see the corollary directly.
argument
The argument is essentially as follows: aliens of primitive culture and biological (in the sense that all its development has been biological, not technological) are a hindrance to a mining corporation that wants to extract a valuable mineral. The corporation takes two parallel ways to deal with this problem: the imposition (Na'vi expel by force) and the absorption (giving culture and goods that can reach an agreement on the "relocation").
The soft path is the introduction of genetically engineered Na'vi bodies controlled by humans to teach language and human culture. This path does not work fast enough, so you opt for taxation.
The problem of declaring a war on aliens is that one of the humans who controls an avatar falls for the boss's daughter and decides to switch sides, resulting in a victory (we fear that temporary) against human Na'vi and expelling the planet. At the end of this human consciousness is replaced in its avatar, becoming one more, 100%, of the tribe.
Special Effects
is, I think the characters do not fall into the Uncanny Valley because the distinction between synthetic and real is difficult to appreciate.
Music
Details to highlight
Is it a sci-fi movie or drama?
Of course, I believe that all progress and machinery that appears is completely real in the sense that may exist in the next century. The mech, helicopters and launch vehicles are well made and technology (Even with the human connection-avatar) is credible. The
Na'vi biological evolution is not credible and talk with Mother Nature either. I say this because it is not normal for Na'vi have a mechanism of neuronal communication with many different living species (three, I remember now.) Who is the mother? "Gaia? "Pandora be an Desiccated Solaris?
Theme human religious, largely absent
Being ever so close to death ( Pandora is worse than hell said Col.) I am surprised that no military they refer to life after death or any belief (whatever it is). A full-scale error.
The
Na'vi
Another curious detail is the fact that assimilation efforts have had no success in any of the tribes, even those living away from mineral deposits.
Corollary view it worth it?
The special effects are incredible but do not justify spending so much promotion (50% of the budget), as it could have done the same with less spending. Perhaps less technical quality, but just finishing.
argument is not new, some see an environmentalist ideology, but I see the phagocytosis of a primitive culture. Keep in mind that winning the aliens in the movie, but the question is how long? That is, how long will the mining corporation raze the planet? This detail is hidden from the viewer.
find not expect a masterpiece, using only the finest science fiction film (in terms of quality of rendering synthetic ) history.
