After finishing the movie, I was tempted to perceive the movie in two separate ways. First, I was going to give the movie an A for special effects. Second, I was going to give the story an A-/B+, holding it as high as the new Star Trek.
Thinking about it deeper, you should not separate Avatar's effects from its story. Avatar is a story about the power of perspective; the immersive experience of another culture moves a human beyond prejudice. The 3D cinema experience is also powerful, and brings us ever closer to the characters. Is there an inflection point when our own hearts may be so changed by a story that we will challenge authority? Will technology amplify stories to make these inflection points happen more quickly? Final Grade: A.
