What is the author's style in The Metamorphosis by Franz Kafka?

The story Metamorphosis was originally written in German and then translated to English by David Wylllie. David does a terrific job with this translation, making the transition seamless as he manages to convey Kafka's tale of transformation of Gregor Samsa from traveling salesman to dung beetle. While the transformation is impossible, it is not difficult to see the parallels that Kafka was trying to portray.
