Really enjoyed the movie. Simple, well defined characters. Standard story line. A little heavy on the political and "humanitarian" aspects, but the pacing and visually rich film was quite enjoyable. You can root for the good guy, furrow your brow at the greedy, weep for the opressed, and cheer for the demise of the bad guy - all delivered well! Cameron does it again! 3D IMAX was a great way to see the film.
