The Korean drama "Teach you a lesson" is continuing to reap explosive achievements, winning No. 1 on the Netflix global charts after only 3 days of release.
However, Jin Ki Joo - one of the main actors of the film - unexpectedly became the focus of debate about acting.
Teach you a lesson" tells about the activities of the Department for the Protection of Educational Rights, a fictional organization established to restore order in schools where teachers' authority has seriously declined and students are increasingly difficult to manage.
In the movie, Jin Ki Joo plays Im Han Rim, the only female member of the organization. After the movie was released, mixed opinions appeared online about her performance.
A part of the audience believes that Jin Ki Joo's transition between the image of a teacher and the action-oriented character is sometimes quite awkward.
Other viewers also pointed out that some tense confrontation scenes with students or emotional moments are examples of Jin Ki Joo's controversial acting.


However, in the context of criticism spreading online, new information about Jin Ki Joo's role preparation process began to change public opinion.
In a promotional video posted by Netflix Korea on June 10, actor Lee Sung Min revealed that Jin Ki Joo studied the way female lecturers talk to more realistically transform into the character.
Meanwhile, Kim Moo Yeol said that Ki Joo also sought out experts to be guided and participate in voice training to improve her way of speaking.
These revelations show Jin Ki Joo's huge investment in the role of Im Han Rim, making many viewers think that her efforts deserve more recognition.
Supporters also emphasize that Im Han Rim is not a one-dimensional action heroine. In the original webtoon (online comic) "Teach you a lesson", this character is famous for the combination of courage, a somewhat quirky humorous personality and warmth.
Many people commented that Jin Ki Joo has successfully portrayed those multi-dimensional aspects, helping her screen version to be very close to the original.
Some people also analyzed that Im Han Rim's mischievous and slightly eccentric personality was misunderstood by the audience who expected a more serious and tougher performance.

As the discussion spread, the number of supporting comments quickly surpassed the criticisms.
Audiences left comments: "She is one of the most suitable actors for this role"; "Her action scenes are very good, her appearance is also like Im Han Rim"; "She is one of the reasons why the movie is attractive"; "This could be a pivotal role in her career"...
Even, many viewers believe that Jin Ki Joo deserves to become the "crazy woman" of the new generation of Korean screens, following names that once caused a fever such as Seo Ye Ji, Kim Da Mi, Kim Yoo Jung.
