Books aren’t like television shows. The thing about television shows is that some people will watch them just because there isn’t anything else on. You’re tired and you want to watch some mindless entertainment. You want to watch it now, so you turn to the most interesting thing you can find that is on now. With books, people pick and choose. Occasionally, they’ll pick something up just because it is there, but someone had to make the decision that the wanted it in the first place. It’s interesting because television shows can get by with some of the worst plots. They’ll throw an episode in there that is nothing but clips from previous episodes. Usually, the main character is away somewhere and the supporting cast is remembering what a great person he is.
Can you imagine if we tried doing that with books? Instead of writing a new book, we would just pull chapters from other books to tie together with some weak plot. No one would buy the book, but television producers don’t seem to think there’s anything wrong with doing that with their shows.
