Rick & Morty doesn't exist without Justin Roiland. Adult swim doesn't own Rick & Morty, not in the sense that they can keep it going without JR. The show is him, he is the show. Dan Harmon is amazing and funny. But the show literally isn't the show without JR. It's nothing to me without JR. I may be 1 in billions, but I won't watch my most loved show without its most loved characters/voice actor.
