James Cameron sets new heights for high-tech movies to aspire. With superb 3-D among other exciting special effects, gorgeous multi-layer seamless sets, and well developed characters, I find some of the more critical reviewers in need of reviewer critical care. While some viewers who are science fiction naive might have some minor difficulty, I was impressed with suggestions of a Jupiter-like world seen in the sky (as from Europa), the underlying unifying forces of Pandora, and the ability of Cameron to make us root for the aliens. Not to mention the computer graphic emotive eyes and facial expressions. I actually dreamed about Avatar and flew over waterfalls. Will see it again and maybe again. My first movie review ever!
