Study in Pink review

Good mention of Paul McGuigan here too!


However, before I get to the character of Sherlock himself, it’d be wrong not to acknowledge just how the opening scenes also highlight very quickly just how tight Paul McGuigan’s direction is.

McGuigan, whose background is movies such as Gangster Number One and Lucky Number Slevin, is a brilliant, brilliant choice here. Throughout A Study In Pink, his camerawork is unfussy, and he applies a filmic version of the laws of thirds to many of his frames. It’s to great effect, too.

Furthermore, come the big climactic scene, he’s happy to ground his camera, eschewing close-ups in favour of having two actors talk to each other. It’s at the point where Sherlock confronts his nemesis face to face that McGuigan’s camera moves the least. Granted, the quality of the written material enables him to do this, but he wisely figures that we’re interested in seeing the story being told, rather than any distracting gimmickry. As such, McGuigan’s steady hand is very welcome, indeed.

He also employs some terrific little techniques, specifically the text messages appearing on screen, which we first see during the aforementioned press conference scene. This too could have been a gimmick in the wrong hands, but it’s used sparingly, and to give the audience pieces of important information. I really liked the way he staged the foot-chase after the cab, too, taking advantage of Mr Holmes' inner-satnav.

What villains can we expect in Sherlock series 3?

It lifts my heart to see them mention my fave idea for a future villain!

Not all of Sherlock’s antagonists are murderers or fraudsters. One story that positively cries out for a modern reworking is The Adventure of Charles Augustus Milverton. The slimy individual of the title is a professional blackmailer, profiting from the secrets of the rich and famous. Holmes manages to embed himself in Milverton’s household at the behest of a wealthy and desperate client, only to find that another of Milverton’s victims has a rather more permanent method of silencing the villain. The concept of the heartless blackmailer and his misdeeds recast within a new, modern world of 24-hour celebrity culture is appealing. After Sherlock’s brief foray into that environment during The Great Game, the prospect of more fish-out-of-water shenanigans makes this one a good bet.

Sort of, I have posted about it before.
This guy wasn't targeting 'celebs' in so much as just affluent women. He did it over a 12 year span, and Holmes absolutely HATED this guy. He was one of the few villains that really made him angry.
In the original, the victim kills the villain and Sherlock & Watson witness this, but they do nothing as far as reporting it.
They ensured  no evidence was around and slipped away straight afterwards, the police had a vague description of the 2 men seen running from the place but no-one was ever caught.

I can see a lot of potentials in the story.
