Why do you think the film does not have some of the cool moments that are in the book?

BECAUSE THEY ARE IDIOTS AND DECIDED TO CHANGE IT. PLUS THEY ONLY HAVE SO MUCH TIME FOR A MOVIE BUT PERSONALLY I WOULD'VE LIKED THEM TO STICK TO THE BOOKS A LITTLE BIT CLOSER. STEPHINE WROTE IT THE WAY SHE WANTED IT PEOPLE SHOULDN'T CHANGE IT. I LIKED THE BOOK BETTER. THE MOVIE DIFFENTLY NEEDS SOME IMPROVEMENTS!!!!
