Loved it! The special effects and the Na'Vi characters were so real that one gets completely lost in the movie immediately. The story was well done and amazingly believable. The film' s almost three hour length, without intermission may be problematic for some viewers, but most of the audience remained glued to their seats through the entire performance. I thought that the visuals were fabulous and I was not off-put by the 3D format as I thought I would be. The acting was so so, except for Sigourney Weaver;s performance, as one would expect.
