Do you think it is as good as the review said? ,F: It's a good film, but not as good as the book. I think some of the story was missing in the film. ,M: Yes, but you couldn't possibly fit everything that happens in a 200 page novel into a 2 hour film. There simply isn't the time. ,F: I know, but the director should at least try to follow the story. With this film, he left out some important people and even changed the end. ,M: Well, perhaps he thought he was improving the story, Karen.
(A) F: He did. His film is far more realistic than the book. I like it. (B) F: I am really sorry, I did not catch that. Would you slow down, please? (C) F: Obviouesly, the book is better than the film, though he changed nothing. (D) F: He might. But I still like the original book than the film.
