I saw avatar at an imax theatre with the 3-d glasses. I was nervous at first that the glasses would bother me and maybe i would get motion sickness during the movie. Especially in a sold out theatre. I had no problems with that though. The 3-d experience definetly enhances the movie. I would recommend this movie to others as long as it was in imax. The story line was good and although it was a terribly long movie it didn't drag on and on.
