I found this movie to be delightful as are ALL the movies. However, the scene of the Borough being attacked and burned was not only NOT possible due to charms, but an unnecessary scene. The other part I thought was crucial was the battle at Hogwarts school between the Death Eaters and the Order of the Phoenix. I give it 4 stars..it was funny, magical, intense, hardly ANYONE moved once the movie started.
I still think that THE CHAMBER OF SECRETS is the best book to movie adaptation, with THE SORCERER'S STONE right behind it.
