Well, I just saw the movie.
And may I say frankly, if you have read the book. DO NOT see the movie.
Although I may sound a little harsh, they unfortunately shortened the whole tale into a brief outline.
Certain characters; that were to my opinion very very important, didn't even make appearances throughout the whole movie. Overall, I found it a disappointment to all true Paolini fans.
The only savior of this wronged tale is the utterly excellent score which accompanies the movie.
