I saw Avatar first in 2 dimension. I fell in love with the story and the beauty of the people and their planet. Because I wanted to see if the two dimension viewing could be improved on, I went to the IMax 3D. It was fabulous. Two hours and forty minutes flew by. I was never bored at the second viewing because 3D brought out minute details missed in the 2D. I recommend every one of any age see this movie. They won't be disappointed!
