At lunchtime in work, my friend was reading an article about the ten worst couples in literature from The Guardian in which worst means incompatible or better off apart. I didn’t really rate it as a list though, because for many of these books (Revolutionary Road, The Great Gatsby, Jane Eyre, Bridget Jones’ Diary) the reader knows that the relationship featured in the article is meant to be fundamentally flawed.
Also, major clanger on the Anna Karenina one… “Anna and Vronsky would have had life a lot easier if they had just stuck to their marital partners – Anna especially.” Well yeah, since Vronsky wasn’t actually married… :S
But how would you define the worst couples in literature? For me it would be a couple that I didn’t believe in, or didn’t care about.
