It's a really good series. The feeling they create, the visuals of the setting, and the overall mood all fit together well with the story’s depiction of a world falling apart, where people are separated by how much money they have. Those in charge—basically, this company that seems to control everything—are without morals, and unlike what we see today, they put making money and gaining power above the wellbeing of others. The narrative focuses on one man who overcame hardship and brought other people together to confront a formidable opponent while attempting to safeguard those who are vulnerable. Kim Eui-sung and Nam Kyung-eup both deliver fantastic performances, but Kim Woo-bin is truly remarkable. You can sense his rage, inner strength, and resolve as he plays the role of deliveryman 5-8; he conveys more with just his eyes than many actors do with their entire body and facial expressions. Esom’s acting was also very good. I enjoyed the action sequences; they seemed quite well executed. I believe most viewers can relate to characters living in a shattered world, so you'll be able to watch the whole series without getting bored. I attempted to write this review without giving away too much of the plot. However, I have to say something: I’ll never understand people who write reviews after only watching something for fifteen minutes or so. It takes them longer to sign in and type out their uninformed and foolish thoughts than it did to actually watch. You need to experience something fully before reviewing it—consider the acting, the message, the complete story—and then decide whether to recommend it or not. Who decides based on just part of an episode? And speaking of reviews, the one I read about women and some "woke" thing... I honestly have no idea what that person was going on about, especially when considering this series. I’ve watched it and I suggest you do too; it will both entertain and provoke thought.
