Query: Big Dissapointment

Having just finished Sabatini's classic adventure story, I really looked forward to seeing how Hollywood put the story on film. What a dissapointment! Simply, the book is great and the movie is mediocre. It is almost a completely different story. On the positive side, there is a nice sword fight in an Opera House. I would not recommend this movie for anybody who loves the book.
