Jane Eyre has very long sentences containing very entertaining dialogue. I like that. And there's more or less subtle critique on the rich assholes of that era.
If you want a modern and fun take on Jane Eyre: "The Eyre affair" by Jasper Fforde is a very funny and action rich read and the start of a series of very entertaining bikes about "book world". Fforde really is in love with his topics and tropes and personnel, and it shows.
