Query: A Creative Fantasy of Intelligent Extraterrestrial LIfe

I limit my review to the visual effects. They are very good. The planet Pandora is inhabited by humanoids that have blue skin and the stereotyped pointy ears. They also have tails, and are animated by beliefs that are a cross between animism, ancestor worship, and eastern philosophy. These humanoids ride on "horses" that resemble dwarf sauropod dinosaurs, but which breathe, insect-like, through holes on the sides of their bodies. The humanoids also tame, and ride bareback, on pterosaur-like flying creatures. All of the foregoing adds up to dramatic battles scenes against a seemingly technologically-advanced invader.
