Amanda the Aspiring TV Writer:
"I want you to think about tracking the feelings of your characters. It's a note I've gotten a few times and it's starting to sink in. Sometimes we think about our scripts in terms of plot, and that's certainly understandable - but how do your characters feel about all the things that are happening? What are their greater emotional journeys and arcs? Do they feel differently in the end than they did in the beginning? Is there consistency? If there are changes in feelings, are they on purpose? Understanding what our characters are feeling is an important step in understanding their motivations, and thus being able to root for (or at least be interested in following) people. That's how I see it, at least."
That's how I see it as well. Anything in a plot can be justified and given depth through character emotion. Absolutely anything.
