This episode is about friendship and it unleashes the full power of Benedict Cumberbatch as one of the finest actors of his time. They have written an episode that captures the wedding ceremony and all of its insipid traditions with the feeling one has to celebrate a sea change in one's life when one must let a friend go. It is a mature episode that remembers itself at some point as a show about a detective but delivers an experience of empathising with Holmes as a human. It asks the viewer to be a mute participant in this event and take time to look inwardly and, in some ways, solve the mystery of the self. Masterfully done. Hats off.
