Avatar was visually spectacular, and the special effects in Imax are truly incredible. The plot was solid in terms of its outline, but the actual "story" of the movie - i.e., the unfolding of the plot, was relatively fast and superficial. There was not a lot of development of the characters so much as a fast paced move through the plot to get to the action sequences. Another 30 minutes with just a little more downtime from the action that focused on the story would have made this movie five stars. Don't get me wrong, though - I will go see it again.
