Seo Kang Joon is using his facial expressions in his acting for the first time. It’s truly impressive—absolutely remarkable. 서강준은 이번 작품에서 처음으로 표정 연기를 선보였다. 대단하다,대단해. :))))))
It was a great series that knew exactly when to end. Elements like the deliberately fantastical fight scenes, the interspersed comedic moments, and the detail of Kim’s friends wearing the same outfits throughout the show gave it an iconic feel—as did their reputation as the "middle-aged men in glasses." The agent persona suited So Ji-sub perfectly, given his muscular physique. The villain was incredibly charismatic, and the casting was spot-on. The only thing I felt was missing was a strong OST!
