Who are the millions of people who watch, for the 20th time in their life, how Character A does something unrealistically stupid, ends up in an awkward situation, and then spend the rest of the episode being continuously teased over it by other characters, because they're all written to be slightly stupid and low-key assholes.
This is not to criticize sitcoms and reality shows (and people watching them) here, but rather to point out that the same phenomenon you described also manifests with vastly more popular forms of entertainment, so there must be something to enjoying the experience beyond sheer originality.
