For a drama packed with big leads the upcoming OCN procedural Watcher feels remarkably low key. Veteran leading man Han Suk Kyu makes his drama return opposite Kim Hyun Joo and the always hustling Seo Kang Joon. The two men are cops in the internal affairs investigation unit of the police force and further team up with Kim Hyun Joo’s prosecutor turned civil lawyer in investigating police corruption. I already can feel the tension between leads Han Suk Kyu and Kim Hyun Joo in the first stills released above, and Seo Kang Joon seems like the perfect third foil as the young scrappy one to round out this trio battling the forces from within. The drama is from the PD of Memories of Alhambra and Secret Forest (Stranger) with the script from the writer of The Good Wife and Spy and will air in the Sat-Sun time slot after Voice 3.
