I think what you are looking for is a potboiler.

A potboiler or pot-boiler is a low-quality novel, play, opera, film, or other creative work whose main purpose was to pay for the creator's daily expenses—thus the imagery of "boil the pot", which means "to provide one's livelihood". Authors who create potboiler novels or screenplays are sometimes called hack writers or hacks. Novels deemed to be potboilers may also be called pulp fiction, and potboiler films may be called "popcorn movies."

Also there is a term specifically used for written work: dime novel.

In the modern age, "dime novel" has become a term to describe any quickly written, lurid potboiler and as such is generally used as a pejorative to describe a sensationalized yet superficial piece of written work.
