The episode revolves around the children of South Park trying to stop their parents from watching "murder porn", television programs containing softcore pornography that reenact true crime stories.
Randy and the other parents go to the cable company to ask that the lock be removed, but the sadistic representatives they speak to rebuff them, while mockingly fondling their nipples.
At the community center, the children discuss how their parents are now not only continuing to watch murder porn, but are ruining their online experiences in Minecraft as well, blaming Kyle and his app.
The boys confront the cable company's representatives, who are unsympathetic until they learn about the prospective displeasure the parents would have at being unable to access murder porn.
[1] Parker and fellow series co-creator Matt Stone chose Minecraft to be the secondary focus of the episode because they wanted something family friendly to contrast with the adult oriented programming that comprises "murder porn".
[2] IGN's Max Nicholson gave the episode a score of 7.8 out of 10, saying: "After last week's season premiere, South Park's 'Informative Murder Porn' was noticeably better, and depicted a simple but effective premise.
Club gave the episode a B+, saying: "Coming off a hit-and-miss season premiere, [...] 'Informative Murder Porn' keeps the satire local, social, and more consistently amusing in its second week.
