Guy Ritchie’s 8-Hour Detective Series That’s Designed To Be Binged Can Only Get Better

Guy Ritchie’s bingeable eight-hour detective drama can only get better as the series continues. With his trademark style, humor, and action sequences, Ritchie has created some of streaming’s most exciting shows; add in any element of mystery and intrigue, and it’s bound to be a hit, as proven by the director’s recent success on Prime Video’s streaming charts.

Surely, it was only a matter of time before Ritchie returned to the realm of Arthur Conan Doyle’s Sherlock Holmes, after his Robert Downey Jr.-led duology offered a fresh, more adventurous take on the world’s most iconic fictional detective. Now, however, Richie’s most recent Holmes adaptation has taken the character in an entirely new direction. Ritchie, Peter Harness’, and Matthew Parkhill’s Young Sherlock explores the famous sleuth’s life long before he moves into 221B Baker Street and meets John Watson.

Across eight episodes, Young Sherlock‘s first season depicts Sherlock (Hero Fiennes Tiffin) as never before. As a young, inexperienced, amateur detective, he’s more willing to accept help from his family and unexpected friends. However, because this is a time in Sherlock’s life audiences are largely unfamiliar with, season 1 spends a significant portion of its eight episodes introducing and developing character dynamics and Holmes’ budding talents, leaving less time for the more exciting, adventurous scenes viewers may expect in a Ritchie production. Thankfully, though, that will all change in Young Sherlock’s second season.

Young Sherlock Season 2 Can Take Its Mystery To The Next Level

Young Sherlock season 1 has a compelling enough central mystery, involving a secret network of Britain’s most elite minds, the death of Sherlock and Mycroft’s (Max Irons) younger sister, Bea, and the creation of a deadly chemical weapon. The case doesn’t really hit its stride until the latter half of the season, however, when it becomes an international, fist-fighting, explosive adventure. What’s more interesting in Young Sherlock‘s first few episodes is Sherlock’s surprising friendship with the one and only James Moriarty (Dónal Finn).

This unique perspective on Holmes and Moriarty’s relationship is, by far, one of the best parts of the show. For once, they’re on the same side, helping each other during what is one of the most formative periods of their lives. They feed off each other’s energy and intellectual curiosity. Young Sherlock season 1 is almost like an episode of Marvel Studios’ What If…?, asking what it would be like if these two traditional enemies were something else entirely.

The final episode of season 1 sets up a more familiar dynamic for them, as the pair begins to drift apart when Moriarty gets a taste for crime and power. The additional emotional depth in their relationship from season 1 will only add to their story in Young Sherlock season 2. Finn, who delivered an excellent, charismatic performance in the first season — often overshadowing Fiennes Tiffin’s Sherlock — will finally be able to let the darker side of his character shine through.

The anticipation of when Moriarty will turn on Sherlock will almost certainly increase the tension, no matter the case the young detective is working on. Given this version of Sherlock’s world and his most important relationships have now been set up, that case will likely be a rip-roaring, fun adventure, involving more chases, fights, explosions, intrigue, and Ritchie-style rapid-fire dialogue and humor.

There’s nothing left to hold the series back now. Both Sherlock and Moriarty have had their first taste of danger, making them all the more reckless as they grow into more traditional versions of their character — in Sherlock’s case, a less naive one, as well. While season 1’s 84% Rotten Tomatoes critics’ score is nothing to scoff at, surely, the series will be able to improve upon it in season 2.

What To Expect In Young Sherlock Season 2

Prime Video announced the official renewal for Young Sherlock season 2 on April 14, a little over a month since the first season dropped in full on the streaming platform. Though nothing has been revealed about the upcoming season’s plot, Guy Ritchie will return to direct the opening episode, promising a fast-paced kickoff for the show’s sophomore mystery.

Though the trajectory of Sherlock’s relationship with Moriarty is clear, it’ll also be interesting to see how his relationship with his family will develop, particularly with his mother and brother. This is still a much younger, less established, less antisocial version of Sherlock, after all, and the series should continue to play with those unexpected aspects of his character.

More Moriarty is certainly no bad thing, either. Giving him more of his own perspective, away from Sherlock, will give this version of the Holmes story an edge that no other adaptations have had before. A closer look at the inner workings of Moriarty’s budding criminal mind would add a much darker, more psychological tone to the show, a nice counterbalance for what promises to be an action-packed second season. Young Sherlock can only get more exciting from here.

All episodes of Young Sherlock season 1 are now streaming on Prime Video.
