A series of acts builds the largest structure of all: the Story. A story is simply one huge master event. When you look at the value-charged situation in the life of the character at the beginning of the story, then compare it to the value-charge at the end of the story, you should see the arc of the film, the great sweep of change that takes life from one condition at the opening to a changed condition at the end. This final condition, this end change, must be absolute and irreversible.
