It ranges from comedy to drama, similar to the style of futurama or finalspace. simpsons and family guy like to put you in your comfort zone, whereas rick and morty take you out. you can rewatch simpsons over again for that reason, but not with r&m. it's cathartic the first time you watch it, after that you're jaded and can't watch it again. I've seen the same said about an excellent japanese anime "Now and then, here and there"
