Drove 150 miles over two mountain passes so my 6 year old twins could see this in IMAX 3D in Denver. Of all the movies we saw together it was the only one where they didn't move or say anything, they were completely immersed in the movie. I am surprised it has not been re released in IMAX 3D again because of the experience it offered, it actually snows on you. Should it ever come out again in IMAX 3D and you only saw the 2D version don't miss the opportunity. The twins, now 21, have said if it ever shows again in 3D we are going to see it again.
