So Cartman swaps places with a black woman from an alternate Universe where everyone is a black woman, in reference to Disney etc “blackwashing” white characters in movie remakes.
But nothing seems to actually happen, just some crap about Kathleen someone and the fact Cartman is now a black woman for almost an hour which is somehow supposed to be funny in itself? The whole thing just seemed to be an excuse so we can see how the characters of SP would look like “if they were a black woman”.
The subplot about Randy and his oven door was way more entertaining and actually had a storyline to it.
So you don’t get it because you don’t know who Kathleen Kennedy is or who disney is and how they made terrible decisions on pretty much all movies
