The computer-enhanced animation and 3D made this a movie worth watching on the big screen in a theatre.
It's a bit of a let-down that the film does not follow through on it's original promise by being more innovative in it's casting and scripting to equal the innovations in it's visual effects. However, the sheer brilliance of the visual effects helps one to overlook the shortcomings of the story line.
Some have labeled the film as anti-military and some have said it's racist. I disagree and feel that the main message was one of respecting others and advocating understanding of their traditions and also respecting the importance of the environment and the balance of nature.
