I've seen more than 150 KDramas and this one made me the most disappointed. It's sooo overrated. Yes, the cast is brilliant, but the great cast doesn't always make the drama great as well, and "The heirs" is the best example for this. The reason I give this drama 3 points, instead of 1 is - Great cast, great fashion/outfits/design and that's all. No chemistry between the main actors, bad storyline, tasteless music.
