I have a shortlist of movies that are better than the original books, and an even shorter list of texts where the movie and the book are both perfect, and the boss of that second list is The Princess Bride.
“And that's when she put her book down. And looked at me. And said it: "Life isn't fair, Bill. we tell our children that it is, but it's a terrible thing to do. It's not only a lie, it's a cruel lie. Life is not fair, and it never has been, and it's never going to be.”; --William Goldman, The Princess Bride
