I have seen all three. The regular version of this film is gorgeous, it is stunning and vivid and it is a good movie, but not a great movie, and I gave it only 4.5 stars at first. The 3D (regular) version is different. It's not as vivid or amazing, but it's extremely immersive, although the three layers and sometimes choppy movements leave aught to be desired. The IMAX version, however, combines these two flawlessly, with a smooth, vivid, amazing and astounding experience. The movie itself is wonderful, it is Lawrence of Arabia, The Last Samurai, Dances with Wolves, Fern Gully, etc. but retold with style. Do not miss out on this, and I must must say please see it in 3D at least if not IMAX 3d (which is the best)
