I though the book was good, but unlike most diehard fans, I believe that most of the changes made for a better film. Making Malcolm more of a definite lead rile was a good move. Having the hunters capture live dinosaurs rather than just eggs made it a lot more dramatic. Having the hunter and gatherer camps team up to find safety made for a lot more interesting drama between the two groups, the book only had sarah meeting them briefly. And while some found the T-rex in the city a bit silly, I thought it made a much more spectacular end than just another raptors breaking into buildings that the book ends with.
What do you think?
