I went to see Harry Potter and The Deathly Hallows Part 1 yesterday, and I was more than enthusiastic with the results. I was paying strict attention to the scenes and details and I found only three important things that they either altered a little bit or left out entirely.
Compared to all of the other Harry Potter movies, this is phenomenal.
The only major things they left out or changed in the movie that JK Rowling wrote in the book were the goodbyes between Harry and the Dursley family, Hedwig‘s death (sadface), and a mural Luna Lovegood had painted on the ceiling of her room.
In the book, Harry’s cousin, Dudley Dursley, gives Harry a strong hug goodbye and confesses how he never hated Harry, not after he saved his life in Book Five. In the movie, however, Harry just watches them drive away in their car, never to be seen again.
