The best parts were the incredibly beautiful scenes around Pandora, more of Cameron's inspiration from undersea life. The metaphorical plot of European "civilization" raining genocide onto helpless indigenous people was as subtle as one of their monstrous attack helicopters. About 2/3 through I expected a satisfying ending; it faded to black; but then it faded up again on another 45 minutes of very loud violence! Movies are supposed to suspend disbelief, and for most of this movie it did, but the final battle scenes in which the NaVi with bows and arrows defeated the advanced weapons of the humans ... well, I wanted the NaVi to win, and I tried believing they were winning, but that was too much of a stretch of my imagination.
