I saw it, and I was very irked by the climactic fight. There's basically a 15 minute battle where all the "mercs" that you saw as allies in the first hour and a half are now suddenly the enemy and to be mowed down, tossed out of airplanes, crushed, pulverized, burnt and completely destroyed without the slightest hint of remorse.
Cameron wanted to pull a Pocahontas, fine. But a filmmaker of his magnitude had the opportunity to depict a realistic view of the impact that senseless slaughter has (much like he did with the Naavi's hometree scene) in a thought provoking manner, and he missed it in favor of gross oversimplification. These guys were the "good guys" for the first hour of the movie, and now the audience is expected to cheer their deaths? Come on. 
The movie is great otherwise, very stunning visually. (I've only seen it in 3d) I think the story is pretty allegorical to treatment of Native Americans (I definitely didn't see any Iraq/Afghanistan parallels, other than some choice phrases used by the mercs) and in that regards, it's not incredibly left wing or controversial, I was just disappointed that the story itself was so incredibly simple, and felt like Cameron pulled a Michael Bay and put effects ahead of good story telling.
