on Writing Forward:
Some readers think analyzing a plot takes the fun out of reading a story. They believe that if you reveal the inner workings and structure of a story, some of the magic and mystery will fade away.
On the other hand, revealing the bones of a plot can inspire greater awe for the art of storytelling and can be educational and informative for aspiring storytellers.
Consider professionals like watchmakers or computer engineers or surgeons. Before they fix watches, build computers, or heal patients, they study the inner workings of their subjects. Watchmakers dissemble watches and study their parts. Computer engineers take computers apart to see how they are put together. Surgeons perform dissections in order to fully understand physiology.
Storytellers benefit from doing the same.
