Why Do Some Stories Resonate?

Yesterday I saw
The Best Exotic Marigold Hotel and
loved it—so much that I want to see it again. I woke up thinking about it. Why
do some stories touch us so much that we keep thinking about them? Why do the
characters come back to visit our dreams many times?

Maybe part of
it is the way each character’s story resolves itself—not necessarily happily
but in a just and satisfying way.
