Crime shows are no longer something new in Korean drama, but they still largely follow a formulaic approach, such as any other genre. Placing style over substance is a common issue and especially some of the episodic dramas of the type seem repetitive. It is therefore fortunate that tvN's "Signal" not only seems to have a strong main plot, but that it is off to a great start with its two main features.
While the series is primarily a crime and mystery one, it is very encouraging that the added supernatural element of direct communication across time is more than a mere gimmick. The importance of changing the past and responsibility that comes with it are pretty clearly introduced as something which will be a main obstacle in the collaboration between Lee Jae-han (Jo Jin-woong) and Park Hae-yeong (Lee Je-hoon). If written well throughout, this will be a fresh and entertaining experience.
