The script is extremely well written, most of its dialogues are very detailed and able to live up to its tension. The pacing is great and the storyline spreads out incredibly, the social media war was well thought out and it's quite informative on how the social media business works behind the scene, the main lead who starts from the bottom and eventually becomes a vigilante that purges everyone else stepping in her way. Every trick and stunt in the luxury market reflects on the current society where humans are divided into rankings or levels, it's all highlighted with contrasty cinematography like a wide spectrum of colors. It's just that the ending is a little tame and expected when the war was fought so intensely along the way, but overall it is already one of the better kdrama this year.
