I am old enough to remember TV going from only black and white to color - a major enhancement. When movies went from VHS or Beta to DVD it was a major enhancement. When TV went to HD, it was another major enhancement. The current 3d technology is NOT a major enhancement, IMHO. It can be distracting cause the 3d sweet spot is so small and the images outside are fuzzy or slightly doubled. Frankly, I think that is why we get headaches. I don't think the current level of 3d technology adds anything major to a movie.
