Honestly, i don't know what u mean. Regarding the fact that jake is not more in the movie cos he barely appears in the book. Besides Twilight it's about Bella and Edward and how they get to know each other and fall in love. If u want more Jake well in New Moon u have ur chance cos there is more Jake than Edward in that one.
Well though the story is the same they are two different things.The book is more complete and just gives u Bella's perspective of the story in that sense may the movie is better since it's a summary and though it sticks to Bella's point of view, we can sneak peek some other things that r going on such as the baddies of the movie. But on the other hand the book gives u more details of the personalities of the character, what's going on and Bella's ans Edward's relationship. Besides the movie doesn't explain the vampire's gifts well enough it does not comment on Jasper's gift at all. However, Rob is in the movie so yeah the movie it's better in that way !!! ha ha!!!
