This is an important movie in the Harry Potter saga but be advised the writers, director and producers have taken significant liberties with the details from the book. The teen love angst with Ron was overdone. Yet the relationship between Harry and Ginny was underdone. The treachery of Snape and the death of Dumbledore were too understated. The important elements of the disappearing cabinet, the bezoar and the horcruz made screen time but the books are full of details of those elements that the director assumed (mistakenly) was obvious. The scenery,cinematography, dialog and effects were brilliant. Go see it, buy it later for your collection. The best is yet to come.
