Unfortunately there's a basic word count for reviews so 'Show is dumb and everyone is stupid' will probably be deemed inadequate. So I will attempt to put some more words around that overall conclusion to at least meet the minimum requirements.

Shin Se-kyung (Oh Choi-rim/Choi Eun-seol) puts in an enjoyable performances in this show about a woman who can see smells. Unfortunately she's paired up with rapist, Yoo-chun and so you should probably avoid it for that alone. His character has some kind of traumatic narcolepsy.

Even in the romance scenes, this drama is paint-by-numbers. It consists of a succession of kdrama cliches, jarring tonal shifts and the obligatory serial killer. All of this could be forgiven if the plot wasn't almost entirely driven by people being excruciatingly stupid.

Even the male lead - who starts the show as the Best Detective Ever by virtue of not being a blistering idiot - gets quickly infected with Stupid once he's finally accepted by the crack team of morons in the Investigative Unit. These detectives are played almost entirely for comic relief by a number of quality Korean actors who really deserve better.

The central conceit of the show - the female lead's synesthesia - is treated more as a supernatural power than a medical condition and her emotional journey is regularly jettisoned in favour of the male lead's. This is a common problem with kdramas and this show is one of the worst examples of it.

Show gives us a generic and poorly-drawn antagonist whose genius is regularly achieved by the other characters being exceptionally dumb. We're supposed to think this antagonist is playing Chess with the police, but really it's more like a drunken game of snakes and ladders.

In the end, show is dumb and everyone is stupid. Oh and Yoo-chun is a rapist so you probably don't want to watch this anyway.
