text: The book, while not particularly great, was decent, but this movie completely changes it. A lot of the elements of the story are consistent between the book and the movie, but Dr. Ross' character goes from a creatively written character who lives for money and ends up causing the volcanic eruption with her greed to a heart-on-her-sleeve damsel in distress who won't do anything if she even catches the slightest hint that it might be less than noble. When movies change the book that much but keep the same name, it should be a crime.
