I liked this book because it was something else. The characters are bad people with real emotions. Most novels of that day and age are focused on how characters keep up appearance whilst feeling so much they do not express.
The end went south for me though. The last chapter was a Stephen King twist which felt a bit cheap. If Brontë wanted to write a book about mythical creatures, she should have done so, but not introducing the subject in the last 30 pages. No hints towards fantasy were giving before that point.
