What is most impressive about South Park is its evolution over time. What began as a show based around entertaining toilet humor has developed into the most popular satirical voice in modern pop culture.
With everything this episode, the children's story arc has only just begun; while "Member Berries" offers fewer jokes than perhaps classic South Park episodes, it acts as a rather brilliant set-up for season 20.
South Park's lightning quick production schedule is one of the show's greatest assets. It allows Trey Parker and Matt Stone to lampoon current events at a rate that simply isn't possible on any other animated sitcom.
