Definitely. For one, there's loads of adult cartoons - I really love Bojack Horseman for example. It's very clever and unexpectedly deep. But I also still love watching Spongebob and Fairly Odd Parents, I loved them as a kid cause they were colorful and goofy but I found I enjoy them even more now cause there are so many jokes geared towards adults, which I naturally just didn't get as a kid.
