Agreed, we are.
If somebody tells me that they tought GF1 was a little bit boring I always tell them to read the book and then watch the movie over again.
If you`ve read the book first you understand the movie much better.
For me it`s very important to know what everybody is thinking all the time during the movie.
That`s exactly what you learn from the book.
I only wish there`s was books written to all three movies.
