Personally, I will save myself hours and hours of time and enjoy the movie.
I worded that wrong, I meant a main reason for myself. Obviously there are many reasons books are better than their follow-up movies, but the fact of the matter is the vast majority of books are far and away better than the movies/shows based on them.
World War Z is a recent example of a book being far superior to the movie loosely based on the book (takes the term "loosely" to an all new level). People that have not read the excellent work by Max Brooks have no idea how much different the movie is and I just feel bad for them.
Just out of curiosity can you give me some examples of movies based off books you enjoy?
