Whisper, like the writer's previous works is a slick drama based on the corrupt, the righteous and the constant battle between them.
The show is fairly strongly plotted; no one character is dumb, or weak. Each is willing to outmaneuver, outsmart and throw anyone else under the bus to achieve their goals. The result are ever tipping scales so it's hard to tell who is going to win at any one time. Lee Bo Yeong is great as Yeong Ju, playing her with a hard core but maintaining a certain level of playfulness as well. Lee Dong Jun is not quite as great, partly due to plot restrictions (he's often in the office while Yeong Ju is allowed more freedom), partly due to the actor's limitations of favouring a few expressions. The rest of the cast plays their roles well. And the show manages to stay fairly consistent in quality throughout, which is always a nice bonus.
The biggest issue is that the show almost seems too slick - everyone is grey, often leaning towards black more than white. But the constant one-upping, the double meaning words, the very heavy dialogue based scenes make it hard to fully connect with anyone.
Great for any fans of the screenwriter's previous work or anyone who likes drama about the corrupt, or law based ones. The first few episodes give a good idea of the rest of the show so it's easy to decide whether to continue or not.
