If the cartoon touches on a serious topic (like "lets go to fry these vampires"), then it's not just a children's cartoon, with farewell nonsense or flat humor (in the adult's understanding), but in this cartoon the level of humor and the behavior of the characters leaves much to be desired. And honestly, I believe that showing children "stupid adults" or "stupid villains" is wrong: Don't teach children a low-level understanding about people, they CAN understand a lot of things, just give them a chance. Such cartoons don't do that.
