They've abandoned the mystery format that makes Holmes such a fun character to be around. In an almost literal sense, they've lost the plot.

If this is the end, then it leaves the people who loved the show for its celebration of difference with a troubling message: that difference makes you a hero if you're a white man, and an aberration if you're anyone else.

It seems typically Moffatian that we finally learned more about Mary's intriguing backstory just before we lost her, but the mystery surrounding her work with AGRA proved to be a compelling framework for the episode.

It's a jolly enough episode, but not as thrillingly stylish as some past adventures.

Audience Reviews for Sherlock: Season 4


The momentum was lost and the screenwriter seemed to have lost track of what captivated the viewers in the first place. The episodes are all over the place with no clear connections, it was an understandable disappointment.
