The plot was descent, but we obviously didn't spend IMAX money for the plot. If you're going to go the theater...definitely go to see a visually superior movie, and this is the one to see! I loved how the 3D effects literally jumped out at you, which is a great improvement over the movie "UP" that just added a little depth to the movie. EVEN THE 3D PREVIEWS WERE GREAT (Keep an eye out for Alice In WOnderland 3D and Hubble 3D)!!! Avatar kept my 5 y/o sons attention for the whole 3 hrs!
