People always say that it’s just because the shows aren’t made for you anymore and that’s actually the problem but not the way you think.
The shows are quite literally dumber. Cartoons used to have content for parents as well as the kids. Like sneaking in adult jokes that would fly right over a kids head. Now cartoons are just about capturing attention through flashy colors and constantly changing scenes.
Put on a cartoon made decades ago and the whole family can enjoy it. Put on a modern cartoon and anyone over 12 can’t stand it
