The viewers of South Park are different and if you haven't been following South Park since years, you may not like it. South Park is better than other stupid comedy serials. It does satire on recent events and it always gives a message in a sarcastic manner. People who want to see stupidity in the garb of comedy should stay away from South Park and watch other stupid comedy serials, there are plenty. And foremost if you don't have the knowledge, please don't do a review.
Now talking about this episode, this was a parody on Kony 2012 videos. It is one of the best South Park episodes and certainly the best in this season, so far. Again, people who don't keep abreast with current news and developments may not understand this episode. This episode is a blend of a subject of bullying and the main motive of people who want to help this cause, which is just to make money. Social commentary is one of the highlights of this episode.
It was an excellent episode, but all the criticizers of South Park should at least have the courtesy to admit it.
