With “The Six Thatchers,” Sherlock Strays from What Once Made It So Compelling

Sherlock is not particularly good TV. It’s entertaining TV, and it’s frequently endearing TV, but its strengths have never conformed to the current metric for evaluating good, or rather, “prestige” TV—a term so misused, it no longer simply applies to series that are successful in their ambitions to be formally and thematically complex, but to any TV show with the vague sheen of high-budget production design and needlessly shocking plot twists dressed up to seem more novel than they actually are.
The true pleasure of watching Sherlock is less about following the various ups-and-downs of each episode’s mysteries than they have been about spending time in this particular fictional world, with the BBC’s dashing modern versions of Sherlock Holmes and John Watson (Benedict Cumberbatch and Martin Freeman). The show’s best episodes have hewn closely to the central dynamic between Sherlock and John, with the case-of-the-week functioning mostly as an excuse for the two of them to bounce off each other. However, as Cumberbatch and Freeman’s chemistry has garnered a considerable following, showrunners Mark Gatiss and Steven Moffatt have spent each new season upping the stakes of the show, shifting from more episodic seasons to multi-episode arcs, a trend that was kicked off by the death of Moriarty and Sherlock’s faked death at the end of season two in “The Reichenbach Fall.”
Post-“Reichenbach” Sherlock also saw the introduction of Mary Watson, neé Morstan (Amanda Abbington), a character that in some ways, along with Moriarty’s recurring antagonism, became the face of this new mythology-building mode of the show. Last season’s reveal, that Mary was formerly part of an elite group of assassins-for-hire, was a twist so needlessly convoluted, it made the finale’s tease that Moriarty may still be alive seem plausible.
Picking up shortly after last season left off, both Mary’s double life and the spectre of Moriarty dominate “The Six Thatchers.” When we last saw him, Sherlock had killed criminal mastermind Charles Augustus Magnussen, shooting him at point blank range in a bid to keep Mary’s secret safe. Exiled to what would essentially be a suicide mission, everyone’s favorite high-functioning sociopath is immediately recalled when it appears that Moriarty may have returned, having commandeered the country’s broadcasting system to deliver a message: “Did you miss me?”
