Sherlock waits to see where Moriarty will make his posthumous move. One mysterious case in particular baffles Scotland Yard but Sherlock is more interested in a seemingly trivial detail. Why is someone destroying busts of the late Prime Minister Margaret Thatcher? Is there a madman on the loose, or is there a much darker purpose at work, something with its roots deep in Mary Watson's past?

Lacked a focus
1 January 2017 | by TheDonaldofDoomSee all my reviews

I was so hyped for this season of Sherlock, after all it's been years since the last present-day episode. But this one was not anything like what I expected, and not in a good way. First of all, it takes a long time for the plot to get moving, with many irrelevant scenes, which while funny are obtrusive in what's supposed to be the darkest season yet. And the plot itself is convoluted, lacking a clear focus. It's mainly about Mary's backstory, which is annoying as it requires you to recall details from Season 3 which was about three years ago. There's also not much of a sustained sense of threat, very little tension expect in a few scenes. There's no traditional murder case to solve and it feels like a generic thriller rather than a Sherlock episode. And one other thing- that action movie-style fight in the pool is unintentionally goofy and silly, which I would not usually expect from a Sherlock episode.

That's the bad, but the episode is still clever and fast-paced, despite lacking a clear focus. The ending sets the tone for rest of the season, marking a clear change in Sherlock's personality and explaining this season's tagline 'This isn't a game anymore'. So not the best Sherlock episode, but the sets the scene for the rest of the season.
