Seth, webmaster of the official Stephenie Meyer website, was able to attend the Twilight movie premiere with Stephenie, and has posted his review of it on his website (no spoilers, yay!). Here's a snippet of what he had to say:
The first question everyone seems to ask is "was it as good as the book?" The answer is "no". But, I can't think of one good book which had a movie made from it that was as good as the book. I think that it would be impossible to reproduce the type of experience that it is to read Twilight in two hours. Will fans of the book enjoy the movie? Absolutely. Will so-called "Twi-Hards" scream, laugh, squeal, giggle, and swoon (not necessarily in that order)? Definitely—and the chosen order will probably be repeated several times.” Read his full review here.
Certainly, we're all waiting with baited breath to see if we agree with Seth.
