Lawrence, Ben (2017年1月3日). “Sherlock: Cumberbatch's return in The Six Thatchers was worth all the hype - review”. デイリー・テレグラフ. 2017年7月23日閲覧。 “Indeed, the performances from the two leads were both first class. Freeman has made Watson such a nuanced, compelling character, so much more than the poor old sexless duffer drawn up by Conan Doyle. But it is, of course, Cumberbatch’s show and here he looked tanned and lean, ready for action but heading, ultimately, for a fall. Cumberbatch is an actor who invests so much in every scene that watching him is an exhilarating experience and an almost psychological exercise.[中略]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. Clever but not clever-clever, thrilling and gut-wrenchingly sad.”
