This article analyzes the formation of the diversity of the genre of the series of novels “The Dark Tower” by Stephen King, as well as the clips of Robert Browning’s poem in the predominant image of the Tower of Roland and the connection with these genre transformations. In the course of the study, the authors analyze the series of novels “The Dark Tower” and the poem “Childe Roland to the Dark Tower Came”, in particular, the features of the genres, the compositional and stylistic features inherent in these works. When demonstrating the characteristic features of R. Browning’s and S. King’s creative work, it was found that romanticized fantasy per se includes many genre features that differ from the manifestations of horror and classic fiction: fantasy is a genre in the style of high fantasy and concealment, a fairy tale. At the same time, dark fantasy, although it includes most of the traditional fantasy surroundings, is characterized not so much by the interrelationship between its fantasy elements and the narrative, but rather by the connection between the gothic and the horror types of fiction; there is much less science fiction in dark fantasy than in high fantasy. At the discussion stage, it was determined that the best method for translating the lead when working with two multi-genre works is the comparative method, which is based on a simple principle: “What is it like?” As a result, we came to the conclusion that, on the one hand, the use of a methodological method leads to the fact that in the process of text analysis it is necessary to limit the framework to the conventions of the functional style, the genre uniqueness of the analyzed ones, preserving their artistic orientation and the idiostyle of the author. On the other hand, in this way we get the opportunity to carry out parallel search and optimization of data for its synthesis and translation into the exchange part.
