Uhm yap, there are differences, obviously, I don't really think it's easy for a director to include every single detail a book may reflect. Take into account that reading a book is a personal experience, and each of us may have a different perspective of how the films should be. Anyway, I quite find similarities between both the book and the film. And well, maybe the major difference, even admitted by PJ, is the fact that some facts included in the third film actually take place in the second book, so... I don't know. I loved the books and I loved the films...I found nothing much about it. OK, I would have like the films to be identical to the books but the work that PJ and his crew did it's absolutely awesome
wee have to appreciate PJ + cast + crew for making an incredible job. but there's always something to nag about
