The plot echos very familiar scenarios of people with limited technological ability pitted against intruders with more advanced technology. Beyond that the movie portrays an alian civilization and culture that is completely believable as presented. It was simply amazing how Camron created and presented the alian world and its inhabitants in a most believable mannor. The images of the Na'vi people are absolutely real along with their language and cuture.
Simply the best movie I have seen in both 2D and 3D.
