Exceptionally well written, well crafted, and well acted! The film is so designed that it enables viewers to experience what it is like to be afflicted with Alzheimer's. The disorientation, the fear, the sorrow, the anger, the confusion. . . . . all these are not simply in the world of the film or in the mind of the protagonist. They are in the minds of viewers as well. This is surely a triumph of film-making. No other medium could have accomplished such a rare thing.
