This is a masterpiece by Park Chan-wook! What a director, what direction, what a plot, he is perfect. And Choi Min-sik, what a performance by him! I loved it, I can't imagine anyone else playing Dae-su, he is literally perfect for this role. As for Yoo Ji-tae, I have no words for these two actors; I'm literally speechless. Perfect performances by these two, and the cinematography, atmosphere, color grading, and music, these things are perfect and well-written. The pacing is perfect too, it won't bore you for a second. Literally a perfect movie with great action, truly great action, and it's a very emotional movie too. I have no words for Park Chan-wook, what a director, and everything is perfect, more than perfect!
