The only way to see this movie is in IMAX 3D! It's worth the price and the wait. Amazing special effects, as usual, but...and here's the caveat...a little too much "preaching" for my taste. The "tribal Indian" connection is VERY obvious, as is the unmistakeable environmental message. Enough preaching, already, just tell me a story! All in all, a great movie-going experience and not to be missed, in spite of the messages.
