Watson has reimagined the iconic character of Moriarty in an intriguing way, setting itself apart from traditional adaptations of Sherlock Holmes. Notably, Sherlock Holmes himself does not play a central role in this narrative; instead, the story unfolds after his passing. The focus shifts to Dr. Watson, portrayed by Morris Chestnut, who navigates both his professional obligations as the head of a medical research facility and the personal challenges posed by a traumatic brain injury. Throughout the series, he finds himself ensnared in a web of manipulation orchestrated by Moriarty, a character brought to life by Randall Park, who is determined to disrupt Watson’s life.
In a recent interview with ScreenRant at the Critics’ Choice Awards, Park elaborated on his interpretation of Moriarty, highlighting what distinguishes this portrayal from those seen in previous iterations. Park describes his character as more subtle and layered, offering both surprises and an unassuming nature. He also hinted at his recurring presence in the series, particularly stronger in the latter half of the season. His full statement provides insight into this complex Moriarty:
Oh, yes. I’m popping in and out of the season. I recur on the show, more in the second half of the season. I think this version of Moriarty is, by design, a little more surprising and unassuming and someone who kind of blends in really well with the surroundings. I think that’s kind of the point of him, and it makes him a little more dangerous in that way.

A New Role for Watson





In this version, Watson is positioned as a decidedly different protagonist. As the lead character, he assumes the mantel of the Great Detective, serving not only as the chief medical investigator but also as the primary obstacle to Moriarty’s schemes. This is made more challenging by Moriarty’s insidious infiltration of Watson’s team through a concealed agent, who collects rare genetic materials for nefarious purposes, targeting Watson’s humanitarian efforts.
While many medical procedurals feature lackluster rivals predominantly in the form of inept administrators, Watson diverges from this pattern. Initially perceived as a bid to mimic the acclaim of established shows like House or Benedict Cumberbatch’s Sherlock, it instead presents a clear and formidable antagonist undermining Watson’s altruistic aspirations. By featuring a Moriarty who is both subtle and scheming, the series gains an edge over other medical dramas and adaptations of the beloved detective stories.

A Fresh Take on Established Lore

Traditionally, Moriarty has been viewed as a character characterized by his subtlety; however, the uncommon depiction of an “unassuming”villain adds a new dynamic to his role. The character, as characterized in Arthur Conan Doyle’s originals, is often arrogant and menacing. In contrast, television Moriarty is portrayed with a friendly demeanor, marked by frequent smiles, making him an unpredictable and complex antagonist for Watson. Such a transformation highlights Moriarty’s intelligence but redefines him as a non-traditional villain, perfectly suited to the show’s focus on medical dilemmas intertwined with detective work. As the series progresses, it will be intriguing to see just how deep Moriarty’s dark undertones will become.
New episodes of Watson are set to air on Sunday, February 16 at 9 p.m. EST on CBS.
