From my modest literary experience I found a trend, which I will call The Bronte Paradox. Despite the family connection and the similar time period, Charlotte and Emily have a different writing style and distinct themes. I judge this by comparing Charlotte's Jane Eyre and Emily's Wuthering Heights. If I didn't knew they were sisters, I would have never guessed by simply reading these two novels.
Wuthering Heights is the grim love story of the rich daddy's girl Catherine and the violent and primitive Heathcliff. Their love is predestined to a tragic end due to the difference in social class. After Catherine's death Emily depicts with a great imagination Heathcliff's physical and mental cruelty. I enjoyed this gothic novel because it is very far from the traditional love story. Catherine is capricious and inconsistent; she marries Edgar, her cousin, because of his social status, but she remains in love with Heathcliff throughout her whole life. Heathcliff, on the other hand, is not the typical white knight. Quite the opposite - he is brutal, cruel, morose, and ill-mannered. Surprisingly, the novel doesn't end with Catherine's death but continues to explore Heathcliff's change afterwards and the destiny of their children. Without unnecessary sugar-coating, Emily Bronte gives us a non-conventional love story, which is highly influential.


To conclude, I would just mention that Jane Eyre is the 2nd most favorite English book. I can't imagine why. Yes, one of my favorite novels shares a similar plot - Jane Austen's Pride and Prejudice. The latter, however, impresses with Austen's great use of irony and satire to humour the norms and morals in 19th century England. Charlotte Bronte's novel lacks even powerful language and imagination. Even I could come up with a better story.
If you still want to get a sense of the Bronte literature, I strongly suggest you read Wuthering Heights and then watch the movie. As for Jane Eyre, it is the longest version of Cinderella. Largely sugar-coated, extremely insubstantial, and overwhelmingly trivial.
