Critic Reviews for Sherlock Season 4

All Critics (27) | Top Critics (7)

It's a jolly enough episode, but not as thrillingly stylish as some past adventures.

Apr 11, 2019 | Rating: 3/5 | Full Review…

Frankly, it's just a shame the BBC only bothered to make the finale worth watching, rather than the whole series.

Jul 9, 2019 | Full Review…

The stories were plodding, melodramatic garbage and the episodes weren't even well made.

Mar 13, 2019 | Rating: F | Full Review…

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.

It seems typically Moffatian that we finally learned more about Mary's intriguing backstory just before we lost her, but the mystery surrounding her work with AGRA proved to be a compelling framework for the episode.

Instead of truly reckoning with those emotional crises, the Sherlock season four finale is riddled with improbable showiness, melodramatic conclusions, and logic-defying puzzling turning points.

Aug 28, 2018 | Full Review…

The show makes something of a thesis statement. It would've been interesting for Sherlock to explore this idea more, or to do something with its modern setting other than show what Sherlock Holmes looked like solving mysteries in it.

This season of Sherlock was a rollercoaster of emotions. [Full Review in Spanish]

Jul 10, 2018 | Full Review…

Not many shows can handle such swift and complete shifts in tone as this, but Sherlock makes them look positively elementary.

Feb 13, 2018 | Full Review…

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.

Audience Reviews for Sherlock: Season 4

  • Aug 02, 2019
    Please take this review with a pinch of salt, as I'm generally a casual tv viewer. I don't really buy in to the character development in any show... For me, I loved the first 2 series. It was fun, it was gripping, it had the chemistry between Holmes and Watson spot on (as good as I've seen I'm any Holmes production actually), it had the arch enemy and it generally everything I love about Sherlock Holmes. However, I think that in S4 it disappears up its own arse, and, perhaps like Sherlock Holmes himself, becomes insanely self indulgent. Long, boring scenes where they reflect on their lives and loves. For me, that's not Holmes. As I say though, I'm probably not the audience for this confusing character arc. I also really hate being too critical because it's very clear that the writers are incredibly talented and have a love for Holmes the character. This comes out in how they take hints of his character from the original literature beyond the detective and his habits and his loves and his obsessions and amplify them. This can only be labour of love. I think, though, that the best way I can explain my view is with a lazy comparison...I loved the 80s show, the adventures of Sherlock Holmes. Part of the reason I loved it was because it was just a series of mysteries, and adventures, with very good actors playing the lead roles. A mystery is solved, the episode ends, and that's that, move on. I don't see what's wrong with that pure form of entertainment. Perhaps (definitely in fact), I'm just old fashioned and I'm also likely way wrong in my opinion! But, it is my opinion. (I'm sorry Sherlock fans!!)

    This season of Sherlock had some highs, but most of it was confusing and just... not well done, if that makes sense. Sherlock's secret sister? Why?? Why couldn't we have had a normal family member? That would have been funnier. This season took stuff from the pervious seasons and just said "Nope, that was actually a lie! Haha! Fooled you!!"
  • Jul 11, 2019
    A big misstep for the series and a pretty disappointing end but I would lie if I said that I did not enjoy it.

    SO GOOOD OMG benedict cumberbatch #papaBen

    Un final brillante a una serie brillante, la crítica que recibió es la prueba que la audiencia no merece su retorno.

    This season was so good. One of the best seasons of TV I have ever seen. This was my favorite Sherlock season and I wish it got more respect. The ending was a little disappointing, but overall great season!

    Personally I loved the character development, and the show felt stronger than season 3. The final episode, while slightly random, had enough tension to make it feel like a strong conclusion.
  • Apr 13, 2019
    Amazing. Amazingly brilliant. The first episode had me in shock, the second made me cry those silent but quite big tears and the last one had me in its grasps the whole time, even now that I finished it. This is simply put, pure greatness.
  • Mar 28, 2019
    The first two episodes were excellent. They really made my heart ache for both John and Sherlock. The final episode was a slight overreach I thought. The brilliance of Sherlock is that all the criminals could exist, but someone who can "reprogram" a person over the course of a few minutes? Really? Still, it allowed us to have some stunning scenes of interaction between John and Sherlock and that made it almost worth it. Still a great season overall.

    I love every episode and every season. I think the problem is they killed off Moriarty way too fast. So much they could do with that character, and Actor. That dude had the best Moriarty interpretation. What a waste. But, the show is awesome. It's just too bad there isn't more of them.
