I wouldn't rate this movie that high...
Undoubtedly, this was spectacular movie... special effects were quite amazing, however content-wise there was hardly anything new...
Anyone noticed the similarities with Hayao Miyazaki's Princess Mononoke?
Now that you say it... and when I think about it... yes... there is some similarity... but still...
The Director and Producer of Avatar wrote the script for this movie in 1995, but dropped this project because he thought at that time that it would be impossible to start this project, let alone complete it with the current technologies and special effects. But then he saw the Lord of the Rings triology, and then was convinced that now he can make his project come alive on screen.
Let's accept that Avatar has the most advanced special effects and 3D animation in any Movie ever....
