Suppose youve just read a romance novel that has stock characters and a happily ever after ending what kind of literature were you probably reading?

Most likely, you read a fairy tale, or other escapist literature.
Most likely a fiction piece, probably a Romantic novel. By that I mean a novel written in the Romantic period. Something like Jane Austen or one of her contemporaries.
This is an example of "Hack" writing, much like most television soap operas.
