Much to the confusion of viewers, Sherlock was shown both in the modern world, dreaming he was in the 19th century, and in the 19th century, believing he was in the modern world. Even fans on Reddit complained that the shifting between two eras "broke" the episode, with many calling the ever-changing narrative "overcomplicated" and "convoluted". Forum user Candidate88766 posted: "Unfortunately I think the story got a bit too indulgent in the second half with the constant shifts between the real world and Sherlock's mind palace."
