wtf was that!!! that was so unexpected, the twist is so insane and violent, one of the craziest revenge stories I've seen. Choi Min-sik acting was great especially in the last scenes, he truly brought out the raw emotional torment of the character. I loved how the story makes you question the purpose of revenge, is it ever truly satisfying or does it just turn us into monsters and leave us hollow behind? and that ending... was he smiling out of joy or agony? i think I'll be thinking about that for some time
