Sherlock was always rife with plot twists, mystery, and suspense, and whilst the show certainly deserves praise for its story, it was the characters that made fans want to watch every episode again and again.
The partnership between Sherlock Holmes and John Watson was undoubtedly the most captivating relationship in the show, but there were plenty of other characters who stood out as well.
The villains of Sherlock were almost always captivating. Even the more far-fetched antagonists felt authentic thanks to some great performances and a string of well-written scripts.
Though the show was based on the stories of Arthur Conan Doyle, Sherlock introduced several completely new characters that – far from feeling out of place – were interesting individuals who were crucial to the episodes they were featured in.
Indeed, one of the greatest strengths of Sherlock was how memorable many of the supporting characters were. Despite the fact there was only thirteen episodes in total, the screenwriters always allowed the secondary characters to make their mark.
As such, there are an abundance of individuals who rank amongst the best characters in the show…
10. Eurus Holmes
There was never any mention of a third Holmes sibling in Conan Doyle’s original stories, and as such, the introduction of Eurus took everyone by surprise.
One of the most interesting aspects of Eurus was her various disguises. In ‘The Six Thatchers’ she became Watson’s temporary love interest, and in ‘The Lying Detective’ she masqueraded as both Watson’s therapist and Faith Smith – the daughter of Culverton Smith.
‘The Final Problem’ then put Eurus front and centre of the show as she subjected Sherlock, Watson, and Mycroft to a series of psychological challenges. Though this episode was far-fetched, Eurus’s dialogue – particularly with Sherlock and Mycroft – was consistently captivating.
Despite the over-the-top nature of her character, therefore, Eurus never failed to be entertaining.
