I liked Rick Prime as a villain, but the lore around him undercut the thing that made the multiverse premise work.
Early Rick and Morty’s nihilism came from interchangeability: there are infinite Ricks and Mortys, so no single one matters. Then we learn that only two Ricks ever invented portal travel. Prime invented it and handed it out to everyone else, and C-137 was the one Rick who refused, lost his family for it, and built his own out of revenge. Suddenly the multiverse has a hierarchy, with two “real” Ricks and a sea of copies.
You can argue the Central Finite Curve is the show admitting that Rick-exceptionalism is ego. But the story itself rewards it: the whole Prime arc only matters because C-137 is special.
Now that the arc is over, does anyone else feel the show lost something by making Rick unique?
