Storytelling wise, you've gotta take it as far as you can possibly take it with each individual movie. If you're holding out something for a sequel or some cliff-hanger, that's not how I think of a satisfying story.
Most of us grew up with a very damaging story that something is wrong with us. Gradually - or as in my case, suddenly - we become resolved not to believe this anymore. It takes a dedicated practice to follow up on that resolution, because the conditioning is very strong to keep generating self-demeaning stories.
