Rick and Morty is a great, intelligent show that is one of the most positive influences on society right now. This is epitomized in episode S3E7, "Tales From the Citadel," wherein a nuanced, leftist critique of capitalist society is shown along with silly potty humor which can reach so many more people than the typical leftist content. In addition to societal commentary, the show demonstrates nihilist themes in episodes like S1E6.

Like I briefly mentioned, the show contains rich, nuanced (pretty leftist) social commentary, which is presented in a way that is palatable to a mass audience, something which makes the show the most important, influential show currently on the air.
