The cast give accomplished performances (David Lee is ruthless as June and plays his character's development with aplomb, Sung Joon is wonderfully enigmatic, Kim Kkobbi from "Breathless" does wonders in a small role). Some wonderfully dark humour enlivens the morose story. The direction from Shin Su-wong is great and assured considering the budget (non-chronological storytelling, off-kilter music, compelling cinematography). The compelling subject matter is executed for all its worth and it is very thought-provoking. The story sounds ridiculous, but it is bounded in reality (Will students really kill for good grades?). The ending, while well-done, drags too long. Some of the actors look a bit too old to be high school students\r\nThe pacing can be a bit off (due to over-plotting and lots of flashbacks). SCORE: 8/10 (I would give a lower grade, but I'm scared the students might kill me. Just kidding.)
