In this contemporary version of Sir Arthur Conan Doyle's detective stories, Dr. John Watson is a war vet just home from Afghanistan. He meets the brilliant but eccentric Holmes when the latter, who serves as a consultant to Scotland Yard, advertises for a flatmate. Almost as soon as Watson moves into the Baker Street flat, they are embroiled in mysteries, and Sherlock's nemesis, Moriarty, appears to have a hand in the crimes.

What to Know

Critics Consensus

Sherlock makes a welcome and shocking return, and Cumberbatch and Freeman are game, but it may prove difficult to live up to the lofty expectations created by the series' lengthy hiatus.

3/5
It's a jolly enough episode, but not as thrillingly stylish as some past adventures. Go to Full Review Karl Quinn The Age (Australia) Mar 27, 2018
Not many shows can handle such swift and complete shifts in tone as this, but Sherlock makes them look positively elementary. Go to Full Review James Jackson The Times (UK) Dec 28, 2017
4/5
How great to see Jones let rip after so many down-at-heel roles; even his toothy leer, which reminded me of Alec Guinness's in The Ladykillers, felt award-worthy. Go to Full Review Chris Hansell Cultured Vultures Oct 4, 2019
They've abandoned the mystery format that makes Holmes such a fun character to be around. In an almost literal sense, they've lost the plot. Go to Full Review Eleanor Halls GQ Magazine [UK] Jul 9, 2019
Frankly, it's just a shame the BBC only bothered to make the finale worth watching, rather than the whole series. Go to Full Review Rosemary Collins The Mary Sue Apr 12, 2019
If this is the end, then it leaves the people who loved the show for its celebration of difference with a troubling message: that difference makes you a hero if you're a white man, and an aberration if you're anyone else. Go to Full Review Read all reviews

goni Z @RT27193090 Oct 6, 2026 just. boring and waste of time poor directoions nothing like the previus seasons and why do you have to bring back. one actor over and over again and poor. villan acting all over the 4 seasons See more Ukos W @Redheady Apr 22, 2026 A fun, energetic series. This season is a bit slower than the previous ones, but still not bad. See more Edward L @Glyndower Mar 9, 2026 Not as strong as the previous seasons but the second episode delivers a brilliant performance by Toby Jones as the Jimmy Savillesque 'cereal' killer. and is worth watching for that alone. Jones is genuinely frightening unlike the ludicrously camp Scott as Moriarty. See more Sylvia S. @qxt_circle Aug 15, 2025 New directors took over, and it’s clearly not the same team from Seasons 1 and 2. What’s left is a confusing plot and baffling character writing. Sherlock is still himself even while on drugs, but John—without any—somehow comes across as completely unlikable. Honestly, at this point it feels more like fanfiction. By the way, the pacing drags a lot too. See more Matheus F @matheusf_neto Aug 15, 2025 Not the best season, but the cast are fabulous. The last episode was very decent. See more Brandon K @TheKeizer Jun 7, 2025 Entertaining and well acted, the plot of this season is incredibly ridiculous. It goes from smart puzzle solving to supernatural powers almost, it's not great. See more Read all reviews
