Regarding cherished animated series, Matt Groening seems to have his fingers on the pulse concerning what audiences want to watch. After all, the cartoonist and animator has three distinct shows -- The Simpsons, Futurama and Disenchantment -- which have all done well over the years despite their ups and downs. Nevertheless, fans have always viewed each sitcom as a standalone piece regardless of crossovers or Easter eggs, which shouldn't be the case. These connections, in all actuality, bind the three series in a unique way that not only ties their worlds together but also incidentally allows them to act as a working trilogy.
