This is how a proper monstrous drama should look like, an absolutely much better take compared to some of the Korean "monsterflix" lately that are mostly disappointing. The storyline has a lot of clever surprises along with characters that make hell lots of sense, character motivation is crystal clear even during highly complicated face-offs. The action sequences and graphics are so powerful it's totally top class cinema, the soundtrack plays an even bigger part in progressing the suspense, it's unbelievably well tuned to its fighting scenes. It just works like an extremely solid extended director's cut movie that seriously deserves to be shown on the big screen.
