That theory that Rick killed the original Morty(before that time he and Morty killed themselves accidentally) gets me. Like Rick seems so crazy because the real Morty is dead. And he just wants to be around a Morty that lived in a parallel universe because he feels guilt over real Morty's death.
The show is like Futurama. The exoteric feeling that most people see on the surface is a goofy sci fi show. The esoteric feeling that some can see is that the show is deep. :{D
I love how Rick and Morty are funny, but like South Park, they will address issues in life. Including politics, sexism, and inequality; but they do it with cutting edge humor and clever gags. I love Adult Swim in general, but R&M is one of my faves.
