Avatar was good. The only really unrealistic thing in the movie as far as physics was the floating rocks, but those made for some sick action scenes and really cool images, so it was forgivable. What's the problem? The movie was artistic, and there's nothing wrong with a biochemical presence influencing a religious view. Just because they made a more realistic image of alien culture being far different from our own, as well as decent evolutionary characteristics on Pandora, doesn't mean that it is bad. They just have a different religious belief, so settle down, they aren't hippie trash. Just because movies incorporate territorial connection and loyalty to one's nation to the point of death quite frequently doesn't mean that it shouldn't be used, because that happens, and you can't just exclude such a thing just because it is used a lot. What if William Wallace (real or Mel Gibson) had realized that people as far back as the Sumerians, and possibly beyond that, had used nationalism and loyalty as a basis for defending their homes zealously and decided not to fight Edward because it was not original, well then there would have been no Scottish Wars of Independence, and I'm not going to go into detail but that would have changed a lot of history, and so it shouldn't be removed from movies because it seems cliché.
