Yes there were pieces of the book missing but that happens in every movie! The books are meant to fill u in on Every detail of every character where as a movie isn't, they dont have the time. The Only thing I think would have made it better was a lil more back story on the Horcruxes and Tom Riddle/Voldemorts family and where he came from.(the ring) Dumbledore dying was a sad moment that was changed from book to movie some but what they did I think worked for the movie. Overall I like how they were able to make the movie so fun even with the sadness of the story. The next (2) movies are very serious and so they wont be able to have as much Fun as they did in this movie!! HP Book and Movie Fan for Life!!!
