Critics have targeted "Family Guy"'s reliance on cutaway gags, panning the show for its characterization and writing outside of these gags, and have unfavorably compared the show to contemporaries such as "The Simpsons" and Comedy Central's "South Park"; "South Park" itself has also parodied and criticized "Family Guy" in several episodes throughout its run. The show's dark humor and sexual themes have also led to backlash from special interest groups. The Parents Television Council has attacked the series since its premiere, deeming it the "Worst TV Show of the Week" on at least 40 occasions, and filing complaints with the Federal Communications Commission.
