Next, we'll have an article talking about how problematic The Honeymooners or I Love Lucy is. Heck, I could probably write one myself, but I'm not going to. Because those shows are set in the 1950s, and I don't expect them to be set in 2024. Same thing with Seinfeld being in the '90s.
Regarding the lack of diversity, it's a show about four Jewish friends. So what? Seems realistic to me. People of similar backgrounds tend to spend time together.
