Sad to think that many will miss out on this wonderful experience because of their prejudices towards wizardry and fanciful potions. While this latest and last installment perhaps works better on its own than any of the previous films, its real strength lies in the completeness it brings to the entire series. To get the greatest emotional punch, one must watch these films as if they were one. Start with the first and view a film a day, soaking in the character and situations and getting a greater feel for the real story being told here. In that way, the entirety of the message being conveyed can be accurately appreciated and the emotional resonance can be felt to its fullest.
The series plays out as a fantastic example of story structure not as a template to be followed, but rather as a device for conveying meaning. Buy the boxed set and get lost in epic and purposeful storytelling.
