While every other person seemed to be caught up in the recently concluded “Descendants of the Sun” craze, I was not particularly enamoured by it. Instead, I was attracted to the highly acclaimed drama “Signal“, which was specially aired on tvN for the broadcast channel’s 10th anniversary. Incidentally it took over the time slot from another quality drama “Reply 1988” – what’s with tvN churning out quality dramas helmed by lesser known but hugely talented cast?
“Signal” is a detective mystery thriller with an intriguing element in the form of the main characters communicating through time with the help of walkie talkie. This “communicate through time” storyline has been covered by American movie “Frequency” and Hong Kong drama serial “隔世追凶” (“To Get Unstuck in Time”) where father and son communicate that way, but “Signal” takes on a different form where the link is between two police detectives who had never met each other before but ended up joining hands through time to investigate and solve cold cases.
