omg! i went to go watch it yesterday-11.21.08 i am a BIG fan of the twilight series! so of course i had read the book before the movie, i would recommend to read it before you watch it. my friend said she rather read it after because the whole time i kept telling her: "oh that wasn't in the book" LOL. in the movie they didn't really go detail by detail. i think they moved too fast and they also changed it a bit, but other than that...i think the movie was GREAT! i can't wait til new moon, eclipse, breaking dawn, and midnight sun come out :)
