Morty is a titular character you could really spend some paternal affection and anxious empathy on. He’s not like any one of us, not a thing humans can be.
But even the Rickest human would have to admit: you’re nothing like a character whose entire purpose is creation, destruction, recreation the manipulation of all of space and time life and death meaning and incoherence. He lets us think we’re just as smart as him, like it’s us controlling the universe.
Morty’s a great character because he’s a lot like us and he’s gone through a hell of a lot.
