- Americans Hate Tingle: The film is quite beloved among fans of serious adult Western Animation, despite been barely know outside South Korea. However, there are many haters in Japan, who see it as Koreans ripping off their own animation style.
- Darkness-Induced Audience Apathy: Combined with Eight Deadly Words. While the students they are up against are sadistic bullies who make lives for the "pigs" utter hell, our three lead characters are not above torturing small animals or backstabbing each-other, which will cause many to be even more put off by the already bleak story.
- Out of the Ghetto: For a long time it was assumed that the only east Asian countries that could make indigenous cartoons of high quality were Japan and (to a lesser extent) China, while South Korea mostly did animation for other countries. Then this film came along in 2011 and a lot of animation enthusiasts declared that this was one of the best animated films that ever came out anywhere.
- Some Anvils Need to Be Dropped: The practice of Pay Evil unto Evil can be taxing to mind and body, such as eventual Murder-Suicide of Kyung-Min after his business failed and coping with his role in pushing off Kim-chul—who taught the protagonists on this philosophy—after he refuse to kill himself to spite his fellow students, not only does violence beget violence but it can also create Despair Event Horizon from the trauma that would last throughout your life.
- Unintentionally Unsympathetic: Make no mistake, the bullying Kyung-min, Kim Chul and Jong-suk all go through is undeniably horrible. However, any sympathy for them is lost when they stab a poor cat to death.
