How does Tony Kushner use imagery in Angels in America?

The scenes in Angels in America are both long and short and often overlap each other, occurring on the stage simultaneously. This provides two qualities that are important to epic plots: juxtaposition and contrast. In climactic plots, the story moves forward in a cause-and-effect fashion, with the action in one scene influencing the action in the next. In epic plots, however, the action may alternate between the plot and subplot, with little connection between the two. The effect of two seemingly unrelated scenes placed next to each other is a juxtaposition of action, characters, and ideas, which often produces a contrast that makes the play more meaningful.
