Right from the opening episodes, the film chose an unusual way of leading when the character Ly Boi Nghi played by Bach Loc had a long monologue to introduce the context and character relationships. Many viewers believe that this storytelling makes the film's pace heavy, reducing the initial attraction. Besides, some opinions commented that the actress's dialogue has not reached the necessary clarity and force, affecting the feeling of role-playing.
In the action and climactic emotional scenes, Bach Loc's acting continues to create many debates. Some viewers think that the expressions are not really convincing, making the climax lack weight. Especially, in the scene of separation between the character Ly Boi Nghi and Princess Ninh Vien, the emotional contrast between the actors makes the female lead's performance more compared and judged harshly.
These feedbacks remind the public of Bach Loc's previous roles. In "Chau Sinh Nhu Co", the actress was praised for her ability to express deep inner feelings. However, in subsequent projects such as "Ninh An Nhu Mong" or "Truong Nguyet Tan Minh", she also faced comments that the way she expressed emotions was not diverse enough. Reappearing in a drama project therefore further raised higher requirements for dialogue skills and character depth.
Not only acting, the "Duong Cung Ky An" itself is also commented on as having many limitations. Some viewers believe that the storytelling rhythm is unstable, the investigation line is interrupted by minor details, causing the detective arc to lose its appeal. The image and styling are also controversial when the makeup style and color filter are assessed as reducing the ancient costume feeling that is promoted as the film's strength.
Meanwhile, male lead Vuong Tinh Viet is commented to maintain stable form, but the chemical reaction between the two central characters is not really outstanding. The supporting roles mainly play supporting roles in the plot, not creating a clear mark.
From Bach Loc's case, many opinions believe that this is a common challenge for young actors when transitioning from idol drama to drama. The requirements for voice techniques, depth of expression and self-control require a long-term training process. In the context of increasingly demanding audiences, each project becomes a test for the capacity and career orientation of artists.
