Yes I agree that watchers/readers are not always focused on the main question. In any moment you feel drawn in to a story you might be drawn along by a secondary or tertiary question. Storytellers weave them together into a tapestry of compelling viewing/reading. Think of a single joke you might hear in a show, 'Why did the chicken cross the road?', we immediately think, 'How is he going to try to make this old joke funny now?'. Once a story loses its questions for you, you lose interest in the story.
