The best addition to this film from previously ones is Luna Lovegood. I have not read the books, but I get the impression a great deal was left out to account for time and to make the plot run smoother. Not only has the director changed (again) but the screenplay has a new hand, making the very feel somewhat off. It could also be the introduction of a new crew. This could be because of the subject matter: the students spend less time in class and more time preparing for real world evil. At this point in the series, the story takes a decidedly darker and more sinister turn.

With their warning about Lord Voldemort's return scoffed at, Harry and Dumbledore are targeted by the Wizard authorities as an authoritarian bureaucrat slowly seizes power at Hogwarts.
