"Unlike many of his contemporaries, Hartman is admittedly one of the few who isn't at all interested in creating cartoons for adults, and has often expressed his disappointment in other animators for implying that there is anything wrong with cartoons that are exclusively for children. He even has a pet project Noog Network, an app which hosted exclusively "kid safe" shows. Regardless of one's agreement with him, it is clear that the career path he has chosen suits him."
