Guess I'm in the minority based on other reviews but I loved it. Yes, it's yet another chaebol story, but it's a really good one. Tight script, great acting (with one exception), satisfying plot twists. It's shot really well, great background music, and "who did what" will keep you guessing. There's a decent amount of depth and you're kept guessing about the nature of these characters. And it's only seven episodes so it's very streamlined. It's a great weekend binge.
