Amidst all of the chatter about Avatar being anti-American, anti-capitalist, anti-military, blah blah blah -- which I think is mostly nonsense -- one aspect I had a problem with was the simplicity with which the corporate characters were drawn. Of course, most of the characters were simplistic, but the villains were glaringly typical moustache-twirling bad guys.
The one line that kept standing out was when Giovanni Ribisi's character kept calling the Na'vi "savages." Even the most heartless imperialist plunderer in this day and age (and presumably in the future, when the movie takes place) would not be that transparently hostile. Cameron missed a great opportunity to critique corporate euphemisms. Instead of "savages" Ribisi could have said they have a "progress-resistant culture" a la David Brooks.
