Acting, screenplay, special effects were excellent. The edited story seemed sorta flat, without the richness of human drama the book had. Two items in particular were problematic. 1) Without an explanation about the doorway into the Room of Requirements and what the room is, those scenes would have been confusing to someone who hadn't read the books or seen a movie recently. 2) I'm particularly disappointed with one critical element that was lost. The end of the book finally had Harry understanding the role of love and how Voldemort was actually more enslaved to Harry than Harry was to him. And that Voldemort had, in essence, created the very situation that could eventually destroy him.
