In short, that wasn't my meaning. My line about the quality was in response to the first line of the comment I replied to, where it was said "Even worse, Charles Dickens mostly wrote serialized novels", which makes it seem as if that commenter thought serialized novels were considered of poorer quality than the alternative of publishing in a single volume. My remark about not being similar to a comic run is separate, and is due to how installment novels were not necessarily continual works in progress like a comic.
