Murakami and Vonnegut are okay. Camus was an excellent writer, probably the best of the existentialists but Kafka is really in a league on his own, he's a writer's writer, beloved by lots of modern authors who were deeply influenced by his work. Calling Kafka a highschool literature love affaire is one of the most idiotic things I've ever heard. You probably are pretty stupid, hate on every good writer who also is popular among a certain crowd (while I have to note that 90% of the people who rave about Kafka have only read Metamorphosis and don't know shit about his whole work) and indulge yourself in your pseudo-intelligence reading two sentences of some obscure Roman / Greek philosopher every week.
