Avatar in IMAX 3D was an incredible sensory experience. Even if you are not a technophile, your brain is aware that it is being tweeked in completely new ways. You leave the theater ennervated and hyperperceptive. A must see in IMAX immersion. I recomend a late showing so you depart after dark to a relatively quiet city - it would be a shame to have bright daylight and noisy streets shatter the dreamlike feeling that follows a truly new experience. A wonderful story and well acted with the most amazing attention to detail leaves you feeling as if you have truly been observing another world.
