Harry Potter 4 was so bad. they messed it up way too much. you not only do not see the Dursleys, I hate them but still, but it only focuses on the terminent and everything else no matter how important it is, they left out.
One thing that really bugs me is when a good book is written, they make a movie of it, and then they make a book of the movie. I hate when they do that! What is wrong with the original book???
