It's weird to see South Korea doing an archetypical Japanese high school brawler, not in the least because their cinema usually lacks the dedication and focus to pull off such a specialized genre. But here we are. Tae-gyun Kim's film is completely bonkers and over-the-top, sporting the usual school gang brawls, with some pretty capable teachers thrown into the mix. The action is all over the place, the styling is very explicit and there's only one goal: to entertain from start to finish. Not quite as good as more recent franchises, but the two hours fly by, and that's not something I often say about South Korean cinema.
