Rarely have I been so conflicted about an episode of a TV show. I feel like a mixed reaction is inevitable when you wait three years for something. This show has the problem that while it was busy hiatus-ing and making all of its key players into superstars, another modern-day Sherlock Holmes adaption came along that is arguably better in almost every way. But we're not here to talk about Elementary, or about living in Sherlock's prolonged hiatus hell. We're here to talk about "The Six Thatchers," an episode with some great moments and phenomenal acting, but some off-putting developments to say the least.
Cons:
Okay, so let's start with the big one: Mary dies. On the one hand, this isn't a surprise, for many reasons. Mary dies in ACD's canon, and the story of Sherlock Holmes is, at its core, a story about Holmes and Watson. There's also the fact that Moffat has never successfully pulled off a character arc for a female character, or at least not that I'm aware of. So yeah, I guess I'm not surprised. But I'm still disappointed. The shifting dynamics between Mary, John, and Sherlock were really, really interesting. I think Mary got let off the hook for shooting Sherlock just a little too quickly last season, but that could have been explored here. We have John ostensibly engaging in an affair, which is despicable, but is this a manifestation of lingering resentment because Mary lied to him? Or, even more interestingly, a manifestation of his jealousy, since Sherlock openly remarks that Mary is better at working cases than John is? He should be thrilled that his best friend and his wife get along so well, but is he really? Or is John being forced to choose between a life of thrill and a life of convention, represented by two people he really loves? Or is Sherlock forced to learn to share his best friend, the only person he's ever really let in, with somebody just as clever and engaging as himself?
I could go on. All of those elements made for this trio being a really compelling one to explore. But what did we get? Mary is killed off as the result of a standard revenge plot. Mary's past catches up with her, she tries to run, Sherlock brings her back to London, Sherlock mouths off to the secret baddie, Mary jumps in front of a bullet meant for Sherlock, and dies in John's arms. What I think is so frustrating about this is that, on its surface, this could have been a fulfilling arc for Mary. And yet somehow, even in the instant of her death, this becomes about Sherlock and John. Why did Mary die for Sherlock? Well, they're friends, and I get the sense that she felt like a violent end was inevitable for her. All great things that could have been explored more. Instead, we get John blaming Sherlock, and pushing him away.
