Reconstruction of imagination: the puzzle narrative in science fiction films

As an effective strategy to create suspense and maintain the expectation of viewing, the puzzle narrative is widely used in the current narrative text and is worthy of further investigation. As one of the most imaginative movie genres, there are many representative puzzle narratives in the story construction of science fiction films, which are characterized by the reconstruction of time and space in the construction of thinking puzzles, the semantic reinterpretation in the construction of discourse puzzles, and the construction of the identity mysteries of the subject puzzles. With the rapid development of digital technology and smart media, the puzzle narrative of science fiction films not only has textual significance, but also has the value of responding to the concerns of narrative art of the times. In the coming post film era, the puzzle narrative of science fiction films may serve as a new approach to the ontology of film art in the digital age.
