Livia expires with dignity, going into the good night as quietly as she raged in the light of day. Chase and Company had to edit film footage of Marchand's Livia culled from seasons past. They then spliced the bits into a scene with Gandolfini, as Tony sees his mother for the last time. The interlude looks awkwardly manufactured. You know Gandolfini and Marchand are not in the same room at the same time.
Every camera angle is wrong.
Despite the editing fakery, the feelings of aching for his mother's love are real. Tony Soprano's Mom put a hit out on him. Other moms, of course, extract their pound of flesh in more subtle ways. Livia was the font of much of Tony's anxiety. But her ghost still haunts him.
