Query: Read the book!

If you have not read the book, do not see the movie as a substitute. If you have read the book, don't waste your time watching the movie. The movie (in its 90 min format) is very one dimensional, concentrating only on the romance between Catherine and Frederick. The ending is even different which is unacceptable. Take my advice and read the book.
