There's a difference between peanuts and the eds. In peanuts, adults were definitely around but the words they said weren't understandable. As a result they basically were just background noise. It wasn't the case that the kids felt unsupervised. They still went to school, rode the bus, talked with their teachers and parents (even if you never saw them.) And they never expressed a feeling like the adults were missing.

In the eds, if you'd said "their parents have long been dead and the kids are clinging on to what was left", it'd fit right into the story. Eds had dark and serious moments around the lack of adults.

Huge difference in tone between the shows, 100% agree. I just think they are both sort of lampshading the fact that they don’t have any focus on adult characters (in completely different ways).
