I actually never thought the drama was boring. For me it was just a good drama for relaxing. Though JKS's hair kind of irritated me all the time (come on, why not keep it long?!), I don't think there was any other thing I wouldn't like about it... :D
At first I really didn't like it... it was strange to see Kirin High the way it was in this season... but in the end, I've come to like it! It came in the moment, when I stopped comparing those two dramas and thought about it as about some new one. So... I like it, and it wasn't such disappointment for me...(also discovered some actors I might like in the future, too)
I liked him since the beginning of DH2 (for those who know, I mean the ear moment xD) ... looking forward to his other dramas and films...(and I'm sure that they'll come!) ^^
