Initial Thoughts

You may be frustrated waiting for a third ‘Sherlock Holmes’ movie from filmmaker Guy Ritchie (at this point, you really shouldn’t hold your breath), but he’s no doubt hoping to tide you over with a new ‘Young Sherlock’ that spins the clock back to the detective’s days at college

Script and Direction

Series creator Matthew Parkhill has found a decent basis for the new series, seeing him team up with an equally fresh-faced James Moriarty, and spinning a tale of the Holmes family that forms part of the mystery.

Directorially, Ritchie brings something of his Sherlock-focused movies to the style of the show, though it also settles down from time to time.

Cast and Performances

Hero Fiennes Tiffin is a solid Sherlock, though sometimes overshadowed by co-stars Dónal Finn and Zine Tseng.

Tiffin at least escapes concerns of nepo baby casting, providing some charm and wit to the role, even if the family history angle isn’t completely helped by the addition of his uncle, Joseph Fiennes, playing his father. As his mother, meanwhile, Natascha McElhone is a little sidelined to begin with, but has a chance to shine later.

If there’s one performer with a reason to complain, it’s Colin Firth, who for the most part is reduced to being a blowhard, officious type you can tell is up to no good.

Final Thoughts

The new show might not really satiate those looking for the combination of Robert Downey Jr., Jude Law and the visual trickery of Guy Ritchie’s Sherlock outings, but one out of three isn’t too bad.

And if we truly must have a Sherlock Holmes prequel, at least it has some spirit and offers decent entertainment value.

‘Young Sherlock’ receives 68 out of 100.

What’s the plot of ‘Young Sherlock’?

‘Young Sherlock’ follows the origin story of the beloved detective in an explosive re-imagining of this iconic character’s early days. Sherlock Holmes is a disgraced young man –– raw and unfiltered –– when he finds himself wrapped up in a murder case that threatens his liberty.
