Every movie story is derivative of something. Let's face, it's all been done before, so don't be swayed by the naysayers who decry the simplistic story and the predictable plot. Movies are to be experienced, like a roller coaster ride, which is more than a means of getting from one place to another. And this my friends is a real roller coaster ride of a movie. It is a wondrous fantasy that surrounds you and pulls you in. Fragile creatures floating down like dandelion seeds and sparks floating in the air from burning trees are just some of the subtle uses of the 3D system to make you feel like you are there. If you have no sense of wonder, no ability to let your imagination free, then by all means this movie is not for you.
