Not really into everything that has melodrama, I do love Wuthering Heights, but I also enjoy literature where the character struggles as an individual facing society's expectations of them, or ones that have faced alienation/isolation... and also literature that centers around a theme of retribution for the main character. I also like fantasy stories/traditional fairy tales and folklore as well. More of a center on the individual struggle of the main character, or emphasis on the romanticism/ chivalry aspect. I also like literature that focuses on a social struggle/ historical event, existentialist theme, or something on a scientific/intellectual theme as well. The more old-school romantic of a theme there is, the more I like it.
But yes, I think that a storyline such as Wuthering Heights is VERY 4-ish. Could tack on just about any other story that deals with individualism in a sense. Doris Lessing's literature, Daniel Keyes' 'Flowers for Algernon' is borderline 4/5, Jane Eyre, Dostoyevsky's literature, John Keats' poetry, philosophy of Soren Kierkegaard... tack on just about all of the Romantic writers, there's quite a bit of literature that focuses not only on 4 melodrama, but also the individual and romanticism.
