Out of all these dramas, I've only completed You're Beautiful. But I have seen a few episodes of the others (except Queen Inhyun's Man), and I can completely agree with this list. I don't really know about Reply 1997, since I only watched one episode, but Devil Besides You and Playful Kiss smh. It's not that I hated them, but... they were sort of annoying and frustrated me with some of the decisions they made!
Lee Min Ho and now Yong Hwa... why did the directors have to announce such an awesome cast so early when the drama is going to air in OCTOBER?! Well, at least I'm now assured I'll be watching this. But... does this mean Yong Hwa is back on the second male lead bandwagon?
