The controversy over the unfinished ending of The Mist was mainly focused on the following aspects: 1. The plot lacks logic and cohesiveness: The plot development in the finale is too sudden. Many settings and plot developments have not been reasonably explained, making it difficult for readers to understand the true meaning of the plot and the development of the ending. 2. The character image is not full enough: the protagonist and villain in the finale are too single and flat, lacking depth and three-dimensional sense, making it difficult for readers to resonate and emotionally invest. 3. Plot contradictions and lack of tears: The plot development in the finale is often too dull and lacks real contradictions and tears on the surface, making it difficult for readers to resonate emotionally. As for why the real murderer was the male lead, this was also a controversial issue. Some readers believed that the real murderer was the female protagonist because she was described as a ruthless and scheming person in the finale; some readers believed that the real murderer was the male protagonist because he was described as a kind and responsible person in the finale. His actions and decisions were to save more people. Therefore, the readers had different opinions and speculations about the real murderer.
