Is Pinocchio familiar with the Three Laws of Robotics? Did Wells's Martians fly into the Great Guslyar? What do Harry Potter and Winston Churchill have in common? Why do aliens have such stupid names? Why was Arthur C. Clarke cursed by the Komsomol Central Committee? This is only a small part of the questions to which the author of the Subjective Dictionary of Fiction gives the most truthful answers. Among the characters in the dictionary entries are Ahasfer and Carlson, Mickey Mouse and The Matrix, Aelita and Frankenstein, Conan the Barbarian and Polygraph Poligrafovich Sharikov, and many others - celebrities and heroes of the invisible front... Such dictionaries have never existed before: for Roman Arbitman - literary critic, film critic , a specialist in television series, as well as a science fiction writer - world fiction is no longer an object of study, but his own communal apartment, which he knows from the inside and can tell about many of the residents soooo... Science fiction characters and their creators are his relatives, neighbors, friends or enemies, about whom he writes either with delight and respectful aspiration, or with anger and partiality, at times getting personal to the point of assault. In general, everything is as is customary among close relatives. Those who know little about science fiction will find it interesting to observe from the outside and learn a lot of new things. Well, those who know science fiction well can hardly resist the desire to argue with the author of the book.
