It's clear from this drama that the CSI and forensic evidence programs so common in the US and UK etc. haven't yet made it to Korea. There is constant snap diagnoses at a crime scene, often by detectives and without, for instance, a medical examination of a cause of feath, that for some reason is thought to be irrefutable. A prisoner is strangled leaving ligature marks amd dosed with gas and set on fire with a lighter afyer which the perp escapes out an open window and when the cops finally bust the door open theg immediately call it suicide. So... in a locked bathroom the now dead guy somehow manages to dose himself with gasoline and, without lighter or mstch burn himself up and it erases all signs of ligature marks... Just stupid. Other than pre-SCI bumbling and a woman who hears everything but only sectively (the basis of the show), this is entertaining.
