Jude and Sue are nice, if not psychologically whole, individuals. You wish them well, but Thomas Hardy has decided to sacrifice them to his philosophical views. He burdens the poor couple with society's repressive attitudes toward women, the lower classes, and marital nonconformity. A novel that begins with the hope of springtime, ends in a winter of despair.
It is a pessimistic, depressing story that examines Victorian sexual and societal mores, and for this it was condemned by many critics. Hardy was so affected by this criticism that he never wrote another novel. Instead he successfully turned to poetry, although his pessimism was again apparent in some of his verses (Read for instance his elegant poem "God's Funeral"). Some of the novel is a bit melodramatic, but that is a common trait of many works of the period. My credulity is strained somewhat by the basically non-sexual relationship of Jude and Sue. Sue is described as an attractive, intelligent and even flirtatious woman. Put simply, I could not fall in love with such a lady, and live with her as brother and sister.
I enjoy many Victorian novels because they combine outstanding literature with an exposition of the society of the times. Hardy is one of England's best. Highly recommended, and I strongly suggest that you buy the Norton Critical Edition of this work. In addition to the novel text you are provided with interesting information about the author, and a collection of contemporary and current reviews of the novel.
