I thought it was a pretty cool movie. Besides for the one or two "extreme environmentalist" lines It managed to evade that preachy " save the world" tone. All of the script was very well thought out, and it left no loose ends to leave you feeling that a specific part of the movie was wasteful. The 3-D enhanced the overall experience. You can really tell Cameron took ten years or so out of his life to make this movie. Overall, the movie was really cool.
