Avatar is a shimmering masterpiece of a movie. It is in many respects one of the greatest works of art produced by man to date. The level of creativity anticipates potential futures as well as leads the way in terms of what CGI can teach us.
The screenplay is adequate to the task. It is definitively "Dances With Wolves" and yet is indeed far more complex in terms of its connection to an GAIA hypothesis. The film anticipates an Eden and describes mans desecration of that Eden. It suggests that are sins will travel with us through time and in the film resonates wisdom.
McCarthey writes about the Texas desert and about deserts in general more or less all the time. In effect he is one-dimensional as a writer.
Vigo Morgenstern is too good looking for the role as is the 9 year old boy, not to mention Charlize Theron and Kodi Smit-McPhee.
It smacks of Hollywood marketing and melodrama and rings hollow and false as a result. As a father of a nine year old I was insulted by the forced sentimentality and contrived horrific situations. In effect, though the movie gave the book legs and actually revealed the books weaknesses.
Seeing the movie was kind of like riding through the desert on a horse with no name. That's really all McCarthey's book is ultimately- a mediocre Amercia song.
