Chapters
Most people think, I'll start a movie, I'll start a show, by the end something will happen. That's what they think. Now here's the fascinating part. During that 2 hours, is it getting more romantic or is it getting more frustrating? Which one? Frustrating. It's getting more frustrating. At the end of the 2 hours, do you have any more information to make this decision than you actually did at the start of the 2 hours? No. No, you didn't. Now you make your move, they didn't want it. Do we still have a disaster you waited 2 hours to create? Yes. Yes, seriously, right? This is nuts, right? And here's the wild part. Can you reverse it? No. No. They'll go, well, I can apologize. Does that reverse it? No. No, it doesn't.
