The animated series is not for children. In fact, its goal seems to be to offend as many as possible as it presents the adventures of Stan, Kyle, Kenny and Cartman.
The show has taken on Saddam Hussein, Osama bin Laden, politicians of every stripe and self-important celebrities. Oh, and Kenny is killed in many episodes.
I am not a big fan of that show because of how they draw the cartoon.
My favorite Adult show is The Boondocks because I like the drawing and the draw of those characters look so cute.
