I first saw Avatar at my hometown theater in 2D, it was OK. I saw it again in Real 3D at a theater 2 hours away, it was GREAT. I just saw it again in IMax 3D after a 3 hour drive, WOW, WOW, WOW and WOW. The look of the movie totally changed and the sound was what I was hoping for. THIS MOVIE HAS MADE HISTORY!!
