Sherlock - Season 4, Episode 1 - Rotten Tomatoes

The Six Thatchers



Critic Consensus: "The Six Thatchers" is a welcome return for the much-missed series, and features a shocking turn of events that bolsters a somewhat thin plot.

Episode Info

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 images 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...

Critic reviews for The Six Thatchers

The return of Sherlock has been a return to form and proof that Gatiss and Steven Moffat are two of the most inventive minds working in British television.

The performances were stellar and the fan-servicey moments (Sherlock talking to a baby, not knowing Greg's name, etc) were still fun.

In expanding the world of the show, the series has strayed farther away from what made it so compelling in the first place.

February 13, 2017 | Rating: 6.8/10 | Full Review…

It was at its best when the mystery fueled character revelations and drama, and until that dynamic returns, Sherlock will continue to be a frustrating mixed bag of brilliant performance and second-rate story.

The fourth season premiere, The Six Thatchers, is the first time [Sherlock's] managed to be boring.

All this episode did was rob her of a fitting death. Died from a misdirected bullet from an elderly secretary's gun? You deserved better Mary. We deserve better.
