J.W. Eagen, an author said, “Never judge a book by its movie.”
Movies based on novels, short stories or any other forms of literatures are tough nut to crack. A movie is a director's medium. He projects his ideas in the platform of a screen supported by acting, music, sound effects, story, screenplay, dialogues (sometimes silence) and cinematography. The audience sees the director's perspective when a movie is made on fresh idea or subject. They do not have a pre conceived notion about what to see and expect. On the other hand, when audience watch a movie based on a novel, they are not blank. They have already read and imagined, visualized and grasped the idea in their own various ways. No two persons can imagine exactly similar. When there is difference in ideas, people find it difficult to accept things from other person's perspective. That is human nature. Therefore movies based on literature normally face a lot of brickbat, which is quite natural.
