Inspector Koo (2021) Review


According to Keyeast on the 20th, Lee Jung-Heum’s 12-episode “Inspector Koo”, which became a hot topic as a drama comeback after 4 years, was confirmed to be aired in October as a Friday-Saturday drama on the general programming channel JTBC.

“Inspector Koo” is a comedy detective drama in which a police officer and insurance investigator, who is all about games and alcohol, investigates a mysterious serial murder case that is completely disguised as an accident.

Inspector Koo (Former name: Koo Kyung Yi) is described as a suspenseful investigative interwoven comedy, revolving around insurance investigator Koo Kyung Yi, who is investigating a murder case. Lee Young Ae will take on the role of Koo Kyung Yi, who is in her 40’s, an intelligent woman, specializes in solving many suspenseful and dramatic cases. Previously, Kyung Yi used to be a police officer, but she started living a reclusive life after her husband’s death.

Although currently not a police officer, Koo Kyung Yi is still “passionate” to solve scary cases that bring a sense of suspense. In the process of investigating a mysterious murder, she discovers and confronts an unexpected female college student who is a serial killer.

Lee Young Ae’s first appearance in the new action movie. In the newly revealed trailer of “Inspector Koo”, Lee Young Ae has completely transformed into the eccentric Koo Kyung Ki, completely different from the previous types of characters the actress has participated in.

In the messy and littered house, Kyung Yi was so absorbed in playing games in the middle of the night that he shouted at the screen: “Kill them all, kill them all”, showing intense passion and the spirit of ‘blood fight’ for this woman’s game. After winning, she was overjoyed as if she had accomplished something very noble, raising her hands and shouting: ‘Success!’.

‘Inspector Koo’ releases teaser: Lee Young Ae is eccentric, loves games, and lives a reclusive life after becoming a widow. When the startling caption appeared: “She’s not a crazy person”, Koo Kyung Yi shocked a sanitation worker when she suddenly emerged from a pile of trash, then stood up and left without saying a word. The startled worker exclaims: ‘What’s that? Is that a real person?’.

Finally, the teaser ends with Koo Kyung Yi looking directly at the screen with wary eyes and saying, ‘That’s suspicious!’. Is the suspicious incident that Kyung Yi is referring to a murder case and the suspect is suspected? Watch “Inspector Koo” scheduled to air this October on jTBC. 

This will be the movie to look forward to this October. It can completely conquer you with the smallest details, both the spirit as well as the excellent charisma of each actor has brought the drama to the most suspenseful and attractive level. Let’s watch the drama together!
