I read one critic's review that said Avatar was successful because you cared about the characters. And you do. Practically from the get go. And within moments of the film starting, you forget you're wearing silly glasses and sitting elbow to elbow in a packed theatre. Great film. Very entertaining. And worth every penny to see it in IMAX 3D. (Well it's worth every penny to see it, period, there's just a lot more to see in IMAX 3D.)
