It really depends on the complexity and scope of the story. Some novels can handle more acts and still be engaging, while for others, more than a certain number might make it feel convoluted.
The main story of Cyberpunk usually lasts about 25 hours. But if you're a completionist and take your time to soak in all the details, it could stretch to 40 hours or more.
The number of acts in a novel can vary greatly. It often depends on the complexity of the plot, the character development, and the genre. A simple story might have three acts: setup, conflict, and resolution. But a more elaborate one could have many more to build suspense and keep the reader engaged.
I don't know the specific number of acts in The Shining novel off the top of my head. Maybe you could refer to academic research or in-depth literary analyses dedicated to this work to get that information.
