The supporting cast are some of the most memorable characters, not as good as The Simpsons. The characters are perfect, I love Cartman, Kenny, Stan, Butters, Randy and my personal favourite Kyle.
South park is actually the opposite, it is intelligent, funny and in some places heart warming and sad. When people who only watch Rick and Morty hear South Park, they think it's a very lazy and crude show (I will be ripping my friends' love for Rick and Morty to shreds). I actually think it's better than Rick and Morty.
South Park Is the best TV show on Planet Earth.
