When the first episode of Seinfeld went to air in 1989, it faced stiff competition from a packed field of American sitcoms. By its finale in 1998, the “show about nothing” had redefined the sitcom genre and conquered comedy. Critical to its success was the unlikely alchemy of the four central characters — their navigation of the interpersonal conflicts and petty irritations of New York City life, and their heedless disregard for conventions of morality.

That was the trick: the situations they found themselves in had to be relatable, but the characters themselves could not be sympathetic. They had to be superficial, selfish, inconstant, immature, monstrous — which is to say, “Bizarro” — versions of themselves. As co-creator and executive producer Larry David put it, the guiding philosophy was “no hugging, no learning”.

But, as it turns out, there may just be a kind of moral seriousness lurking beneath the mania.
