Everyone with wrinkles on their brains knows that the book is almost always better than the movie. The book can do so much more! Your personal vision is only limited by your imagination! The little details and subtleties are allowed to breath better! These ads explain it rather perfectly saying, "a big part of the story is lost when it becomes a movie".
People commonly say that books are better than movies. Personally I think it's a straw man argument. They are inherently different mediums and were never intended to convey the same experience to the consumer. You might prefer one over the other, but to say one is better just seems silly to me.
