--Summary--
A provocative, in-your-face kidnapping into the disturbing world of Korean school violence. High quality production with excellent action scenes, visuals, and sound. Gripping and fast-paced story with convincing setup. Reasonable plot progression without major holes, but also some plot convenience and noble idiocy that I was able to overlook. Captivating acting from the impressive young leads and veteran supporting actors added to the realism. Though more a prequel than complete narrative, it's a thrilling prelude hopefully to a well-fleshed out story.

I give it 8 (+0.5), which is very good score reserved for one of the best shows of the year. But it's difficult to rate higher because we've only been given a partial story and the compact S1 doesn't leave room for greater thematic depth or connection to characters. I may bump the rating if future seasons are able to develop this into a high quality, fleshed out story.

--Detailed Rating--
✅ Plot (8.5) - The core of the plot is logical and moves the story along at the brisk pace. In the second half of the show, previously calculated and pragmatic characters like Ahn Soo and Yeon Shi both indulge in some noble idiocy and create a bigger mess for the very people they were trying to protect. In addition, Oh Beom Seok's descent into malevolence appeared too abrupt and unfounded as he betrayed Ahn Soo over minor slights while allying himself with bullies that have tormented him far more brutally. While these plot issues are not dealbreakers, they do stretch the plausibility and detract from the story.
✅ Theme / Message (7.5) -
