A very entertaining and beautiful film. The story is familiar but none the less engaging, and contains a not so subtle environmental message. The polarized 3D, which has been used on other recent films, is well used to help bring you into the story and is not used as a frequent gag as in so many other 3D films. The technology is great, looking forward to seeing more of it. At least until something is developed to show 3D films without any glasses at all...
