This show starts off slow with a lot of over-acting but once you get into the hang of it, it's pretty entertaining. The drama starts off trying to be a comedy with a background of mystery. The premise is a top neurosurgeon (Jung Yong Hwa) comes in to help the police solve crimes related to the brain ailments. I'm particularly surprised by the over-acting of Jung Dong Hwan. He's such an established actor; there's really no need for over-acting.

The pacing gets better around episode 3 when the mystery and crime-solving comes to the forefront instead of being buried in the exposition of each character. Having a story of the week really helps prevent the overall series from getting caught up in the over-acting. Once the show got underway, I enjoyed the weekly lessons and brain science that the neurosurgeon character played by Jung introduced.

Jung Yong Hwa hasn't acted in a lot of dramas over the years, and in this drama, he's as prone to over-acting as the other leads. I can't say that this drama is his best work (I still like Heartstring because the role reflects what he does best - being a kpop idol) but I do enjoy the wide variety of drama roles that he attempts. I got to give him credit for trying new things and sometimes they work out (Three Musketeers, the Package), and sometimes they don't.

In short, don't take the drama too seriously. Watch this drama for a light laugh and take it with a huge pinch of salt.
