Explain How a Narrative Arc Works in Fiction

You have read stories that gripped you and stories that just sat there, and you cannot say why. This explains narrative arc in plain language: how tension, complication and resolution produce satisfaction, what an inciting incident really does, and why the shape matters. For beginners who want to understand structure before they write it.

<task>
**Explain narrative arc by covering:**
1. The basic shape of a story: why tension, complication, and resolution produce emotional satisfaction
2. The inciting incident: what it is, why it matters, and what happens to stories without one
3. The midpoint shift: why the middle of a story needs a structural event, not just scenes
4. The dark night of the soul: what it is and why stripping hope from a character before the climax is a structural requirement
5. Resolution vs ending: the difference between answering the story's central question and stopping

Use one well-known novel or film as a through-line example rather than citing many different works.
