This was a movie that operated on three levels. First it was visually a feast for the eyes as you enter the wonderful alien landscape of Pandora and its intriguing inhabitants, flora and fauna. Second, it delivered the timely message that when corporate and military force lack a moral imperative and are not used for the betterment of mankind (and yes that includes Aliens) , it flounders and ultimately is defeated. Third, it addressed mans connection to the environment. It was a treat to see Sigourney Weaver have a significant part in this movie. James Cameron has produced a timely film!
