Avatar is amazing. The storyline will titillate greenies, families, children of reasonable age (little kids may have a problem with the violence), and sci-fi enthusiasts of all stripes. In IMAX 3D, the movie is a CRIME to watch closer than 25 ft away. The 3d becomes distorted and vertigo-inducing, the effects become MUCH more pronounced where you can see them, but most of the screen is beyond the field of vision, and the effect breaks down. If you go to this movie in 3d, and you cannot find a seat at least 25 ft back, leave the theater and DEMAND A REFUND. I had to leave the theater, and it took hours to get my stomach back. The movie is amazing, watch the 3d version only if you can get a reasonable seat.
