The themes of "This Killer Is Not So Cold" are diverse and can be summarized as the incompatibility between the individual and the outside world, the relationship between people, the fierce cultural collision and respect for life, and salvation. "Individual" refers to the two protagonists in the film. The world they face is an indifferent and distorted space. The scene in the city is a bit like being in a cage. Irregular, distorted, and distorted urban composition can be seen everywhere, and the overall tone is biased towards dark colors. Cities, tall buildings, these are the results of human development, but with them, in addition to advanced science and technology, there are also crimes that continue to breed and spread. The most ironic thing is that the police station, which represents justice and order in the traditional sense, has become the source of evil and violence here. The police station is also one of the tall buildings. It is the authority of the entire society, but it has become one of the main positions of the evil world. The film expresses the director's accusation and distrust of the world and society. The seemingly insignificant narrative is actually exploring the ultimate topic of human coexistence. The film gives the two protagonists a warm and gentle emotional tone, and their expression of "love" is hazy and ambiguous. In addition to love, the various types of elements used in the film are relatively balanced and integrated, forming the style that the entire film should have.
The film allows the audience to see the whole process of humanity from annihilation to recovery. The music in the film is well-made, and the beautiful melody highlights the true meaning of the story, which has the effect of inciting tears.
The film is full of artistic atmosphere, and even the murder scene is as unique and beautiful as a work of art. In the film, the director expressed more criticism of some ugly things in real life. In addition, it also talked about the friendship between strangers and the spirit of devotion to love.
