In retrospect, Seinfeld was a very dark show. Somewhere on YouTube there is an insightful little video essay about how the first few seasons of the show are basically the story of how Elaine, a perfectly decent person, gets drawn into their little circle and over time adopts their awful selfishness and sociopathic behavior to try to fit in. How most of the problems of the show are caused by their selfishness and dishonesty, and often involve significant harm coming to someone else, and they don't care.

I can't even remember which comedian it is, but someone had a bit about how the darkest joke he ever heard was a Seinfeld bit about being at the movie theater and just throwing his drink on the ground at the end for someone else to clean up. Like it's a small thing, but the guy talking about it was genuinely alarmed by the depth of how far he genuinely just doesn't give a fuck and doesn't mind if you know it.
