AVATAR

To me AVATAR is one of the most overrated movies of all time. Yes, it is a very good movie, however there are many people and critics that proclaim it as the best movie of all time. This was on the list of movies to watch for the class, and it came up on several sites when I searched for "Best Nature Themed Films". However I don't really see it as a nature film, I think it draws more parallels to the "Manifest Destiny" and Cowboy's vs. Indian's. Which I guess you could say, is an environmental theme in that the natives who lived of the land and respected and cherished it were being driven off by the white man who wanted to settle and develop the land because they thought the land and its resources were inherently theirs for the taking. 

When his brother is killed in a robbery, paraplegic Marine Jake Sully decides to take his place in a mission on the distant world of Pandora. There he learns of greedy corporate figurehead Parker Selfridge's intentions of driving off the native humanoid "Na'vi" in order to mine for the precious material scattered throughout their rich woodland. In exchange for the spinal surgery that will fix his legs, Jake gathers intel for the cooperating military unit spearheaded by gung-ho Colonel Quaritch, while simultaneously attempting to infiltrate the Na'vi people with the use of an "avatar" identity. While Jake begins to bond with the native tribe and quickly falls in love with the beautiful alien Neytiri, the restless Colonel moves forward with his ruthless extermination tactics, forcing the soldier to take a stand - and fight back in an epic battle for the fate of Pandora.
