Korean series

Who loves Korean series? Raise your hand. I do! Every weekend I enjoy Korean series. Last two weeks I finished the story of "Empress Chon Chu" that was shown on TV every Saturday. The week before I started the new story of "Dong Yi" again on TV though I've finished all by DVD, I think it's quite good sereies.
What's your idea about Korean series? For me, Korean series made a lot of money to both the producers and the stars. Not only the popular stars but also singers that most of Thai teenagers are crazy and willing to pay money for them. On a Sunday in May, I have seen a program on TV that a Thai guy who got scholar from Korean to take singing course was interviewed. He had to stay in Korea for 3 months, he got only house to stay and fee for singing course, but for daily expense he had to pay himself. He told the interviewer that Korean people do both activities intently: singing and acting, he meant that they pay a lot of attention in doing everything. This why Korean series and songs are attractive.
If you have any interesting Korean series to suggest, don't hestitage to tell me.
Thanks in advance.
