Jaroš is a free spirit and his writing is characterized by experimentation. There is a thin line between human tragedy and comedy in his work. He expresses the feelings of his contemporaries, both their joys and their evil side and their loneliness. He uses lyricism, eroticism, absurdity and naturalized cynicism. The novel Tisícročná včela (Millennial Bee, 1979) is perhaps his most famous. Its film adaptation was awarded at the Venice Film Festival in 1984. Literary critics cite the book as one of the best post-war novels.
