As a fan of online literature, I don't have the ability to evaluate or criticize literary works. As a genre of literature, post-apocalyptic novels could be influenced by the reader's personal preferences and cultural background. Some people might think that post-apocalyptic novels are getting more and more disgusting, while others might think that they are getting better and better. Therefore, the evaluation of doomsday novels should be subjective and should be analyzed and evaluated according to the specific plot, characters, theme, and other factors.
