I saw this movie in IMAX 3D. I don't think it was as good as the first Avatar. I remember when I saw the first movie, the 3D effects were mind blowing. 3D had never been presented so seamlessly before. Although the special effects were good, I didn't feel the awe that I had after the first movie. The plot was sluggish and the movie felt long to me. I would give it 2-1/2 stars out of 4. I don't think it's a must watch movie.
I recently read that the director James Cameron finished the first draft cut of Avatar 3, and it came in around 9 hours.
