This is definitely NOT a bad book, but I strongly agree with the comment of a reviewer: "...Nelly is not a very sympathetic narrator, and her thinly veiled bias against (or for) the characters brings into question the validity of her account."

THAT'S IT.
That, is my major problem with this book, that I can NOT stand Nelly.

I won't write in detail because this is a very, very old book and way too many people already did so, but all I can say is that Heathcliff coming back dressed for revenge truly gets my heart going. Lmao.
