I've heard this idea now in several commentary tracks for movies. At some point in the writing/editing process they look the story over and track the emotions, and they make decisions about whether an emotion needs to be stronger, or lessened, or if it's even somewhat inappropriate and needs to be changed to something else. It seems to me they're going for something like a symphony of emotions, a movement through a series of different emotional states that add up to a powerful emotional through-line. It seems like a sound idea to me, but I have yet to try it. Anybody do anything like this or have thoughts on it?
