I. LOVED. IT. Yes, the movie did stray from re-enacting all HBP events, but it allowed the audience to deeply understand the emotions leading up to book 7. Instead of throwing all of the events from the book into the movie, Yates did a wonderful job of explaining the most important aspects without confusing the audience. I came out of the theater feeling so humble and sad for Dumbledore. Just like I did when I finished the reading. It was an awesome tribute to the book.
