Both. The humans are secondary characters to the revenge plot, they're just helpers to the main revenge theme. Neither human not Avatar groups are functional in a family sense. When there's time to be a loving family, no one is (unless someone died). They do work together during battle, but there's almost no friendship, empathy or unselfish love in the movie. The four of us who saw it could think of 3 relationships that were positive or had any sort of positive element to them. One relationship was only a nostalgic scene included so it could be referenced at the end of the movie.
