Q. "Have you ever read a book after watching the movie/television version only to find that you don’t like the book as much as the adaptation?"
I've never read a book after seeing the movie. If I've already seen the movie, I move on. I won't spend the time reading a book that I semi-know what is going to happen. There are too many other books out there to read.
I do, however, like to read the book before seeing a movie adaptation. It doesn't take nearly as long to watch a movie that I might now what is going to happen and I enjoy picking out the differences.
