In the film, Luong The Thanh plays Hoang Dung - a successful businessman, with a peaceful family with his wife and two children. However, a turning point occurs when this character gets involved in an affair with Nhu Trang, who was once taken care of by her family. From then on, the series of family tragedies gradually escalates, with many conflicts in love and morality.
Different from the familiar image before, Hoang Dung is a role with negative colors, even can be considered a villain in the story structure. Choosing this type of character is considered a notable turning point in Luong The Thanh's acting journey, which is associated with gentle, upright male leads in family psychological films.
However, the content and character building create many controversies. A part of the audience reacted strongly to the image of an adulterous husband, saying that the details were pushed to an excessively dramatic level, easily causing feelings of frustration. Some other opinions focused on the emotional segments between the characters Hoang Dung and Nhu Trang, saying that the expression was not restrained.

On social networks, many comments expressed outrage, even directly targeting actors. The phenomenon of "hating" the character to the actor is not new in TV series, but this time it has become more obvious when the role goes completely against Luong The Thanh's previous image.
In the opposite direction, there are also opinions that the strong reaction from the audience partly reflects the effectiveness of the role. The fact that an actor who is familiar with the main line can create discomfort for viewers shows a certain change in the way of choosing roles and expressing characters.
Ignoring the controversy, Happy Ghost still maintains a certain attraction thanks to the close topic of marriage and family. Dramatic situations, although controversial, contribute to creating interaction and keeping viewers following the next developments.
Looking broader, Luong The Thanh is a familiar face of the Southern small screen for more than two decades. Born in 1982 in Dong Thap, he graduated from Ho Chi Minh City University of Theater and Cinema and soon participated in television dramas from when he was a student. A turning point in his career came to him through projects such as "Lucky Land", "Coriander Smell", "Sun Gate", helping to build a calm and approachable male lead image.
Participating in "Happy Ghost" and trying his hand at the controversial role shows the actor's efforts to refresh his image. No matter how effective it is, more time is needed to evaluate, but this is considered a different step in his already quite safe career.
