Kafka’s most famous work, written in 1912 and published in 1915, the "Metamorphosis" belongs to the genre of modernist literature. The fate of Gregor, a lone salesman, expresses a common modernist concern about the alienation effect that appears in modern society. Like other works of this genre, it uses the "stream of consciousness" technique to depict the complex psychology of the protagonist.
The "Metamorphosis" is usually classified as a short story. This is a kind of story about unusual life events with an unexpected ending. The action in the novel is vivid and expressive, centered around a small circle of characters who display unusual qualities. The transformation of the protagonist is a kind of spiritual test not only for Gregor Samza, but also for his family and for the world as a whole. And they don't stand the test. The hero suffered physical death without feeling love and humanity or even compassion, while his family members and the world are slowly dying spiritually.
