I have read some reviews criticizing Avatar's plot. However, I believe the film told a poignant and instructional story about the greed of humanity and its destructive appetite. The characters, human and alien alike, were developed and believable. In addition to these amazing aspects of the film, it was simply beautiful to watch. The special effects and artistry created a realistic alternate world in a way never before achieved. It is a treat to the eyes and the mind. If you can get to see it in IMAX 3D, do it. You will not be disappointed.
