The concept starts off with an interesting premise that could have been developed into an intriguing story. However, it starts to get very shallow after a while, with very little depth to the ideas, boring cliches, one-dimensional characters and predictable plot twists. The series should have ended with 8 or 10 episodes at max, they just dragged it out and made it utterly predictably boring after a few episodes.

Aside from the bad guy, no one else appears to have any intelligence and the outcomes of most episodes are laughable. Namkoong Min does a good job as always, he's debonair, smart and intelligent and stands out from the rest of the cast so much that he's out of place. But the police? They are portrayed as so inept and lacking intelligence that it's laughable. Park Yoo Chun, playing detective Moo Tak in a role that's so siloed, dumbed down, irritating and lacking intelligence it's impossible not to cheer for the bad guy. Detective Yeom Mi's role is a little more nuanced and you can afford to be a little more patient with her but her potential is severely wasted. The FL's role on the other hand was better cast and played - she's supposed to be a simple character without much depth, and you go in with very little expectation about her intelligence and abilities. To that end, she was not bad.

However, after a few episodes, it became so irritating that I stopped watching. I feel this drama does a lot of injustice to the capability and skills of a stellar screen personality like Namkoong Min - if you really want to see him shine, look at My Dearest, Hot Stove League, Awaken, Good Manager, or even a lighthearted comedy like Beautiful Gong Shim where he shines.
