Maintaining the most prominent position is Bach Loc in the role of female official Dai Ly Tu Ly Boi Nghi. The character is built intelligently, bravely, representing the "big female boss" model of the Tang Dynasty. Sharp crime-solving scenes or the scene of "breaking the sacred line to marry off" became moments that caused a social media storm. Experts assess that Bach Loc has escaped the familiar gentle image to express her inner depth, from eyes suppressing pain to a determined demeanor in court. She almost received a "rain" of praise and did not encounter significant negative opinions.
Besides, Dai Lo Oa (as Trieu Ngoc Dich) although not taking on the main line, impressed with her delicate acting style, especially in scenes showing inner conflicts. Old actor Hau Truong Vinh is also highly appreciated for his calm demeanor and ability to control the acting rhythm, becoming a pillar in terms of acting. These three names are considered difficult to find minus points in the film.
Two young faces Trieu Tinh and Truong Duy Na have made clear progress in their positions. Although only playing supporting roles, both built their own character personalities, contributing to thickening the storyline. After the movie ended, their number of followers on social networks increased sharply, many opinions believe that this is a springboard for the two actors to rise in rank in the near future.
A notable case of "reversing the situation" is Trieu Tu Ky. Having been faint for the past few years, she returned impressively with the role of Thuc Phi - a character with a gentle appearance but containing strategy. The climax scene at the heavens is considered by audiences as one of the best scenes in the film, helping the actress "reverse" her image and reaffirm her strength.
In contrast to his colleagues, Vuong Tinh Viet - the male lead of the film - faced a wave of criticism. The character is considered to lack depth, many times becoming faint in key details. Many viewers commented that this role is not heavy enough to go hand in hand with the female lead, causing emotional flow to be uneven.
The clear differentiation in feedback for the cast of "Duong Cung Ky An" shows that audiences are increasingly strict with the quality of characters and acting. The success of the film lies not only in the attractive detective script, but also in the convincing performances. Conversely, any unconvincing link can easily become the focus of controversy in the current fiercely competitive market context.
