Matt Roush says...

Somewhere Basil Rathbone is out there frowning. And it’s unclear how Sir Arthur Conan Doyle would react to this irreverent reimagining of the iconic sleuth as a privileged scamp and borderline delinquent in Guy Ritchie’s flashy, frothy caper of an origin story. Hero Fiennes Tiffin is the cocky young Sherlock, relegated to being a porter at Oxford University, where he regularly upstages the staff and draws the admiring attention of future adversary Moriarty (Dónal Finn). Intrigue involving a Chinese princess (Zine Tseng) with martial arts skills draws the nascent detective into an international conspiracy in the eight-episode romp, which shares the breakneck pacing of Ritchie’s Sherlock Holmes movies starring Robert Downey Jr.
