I have never understood the appeal of this book.
The only thing I've ever ome up with is that they make you read it in school and compared to the Brontes and Silas Marner and picking the way through MacBeth on a page instead of stage, it seems pretty good, and actually might have something to do with the lives of the teenagers reading it, unlike the others.
But why people STILL say they like it, once grown up and exposed to other books, is beyond me.
