I was thinking of seeing Avatar and I see there is a "real d 3D" option to see the movie in 3-D and was wondering if it was worth it for the extra cost? There si a $3.50 difference in cost between the regular and 3-d movies. So far I've been unimpressed with any 3-d movies I have ever seen but this is supposedly new technological stuff that is way better than previous 3-d movies. Anyone seen the movie with this technology and can say that they were really impresse with the technology and worth the cost? This is not IMAX but a 3-d tech.
