That an interesting question! I think that they are interesting because actors are great, story are original and make us unable to think about anything else that the end of the drama.
And for me, european girl, they are more like our culture than japanese so in first it's what make me prefer them.
And I love korean langague...

of course becoz of th actors n also they are really good that's make tkorean drama be so interesting

what interesting is they know the weak spot in human.

Sad, funny and the rest.. i guess its base on the experience the people involve making the dram/movies.

Remaking of their past/experience emotion and can make the viewers relates to is DAM good.

I've never liked watching dramas before until i was introduced to the korean dramas. The first drama that i watched was Sassy girl Choon Hyang. I got hooked on after that.
Korean dramas rocks!

because of the good story and cute actress,wahahahah.cute actress is important

The talent and uniqueness of most of the actors (male & female) is amazing! And the range & projection of their character's emotions is outstanding, totally believable and engaging. I haven't been emotionally touched by a movie for many years until I started watching Korean Movies! The music, the scenery, costumns just beautiful! And alot of the actors are young and yet so professional & masterful! I'm very grateful to have found one of Korea's hidden treasures!

BECAUSE OF THEIR STORIES
AND THEIR CHARCTARES

i just finished watching mai first korean drama , that is princess hours and im seriously seriously ADDICTED. i guess i like them because they hav unique original storyline plus their cast is really good. they know how to express emotions..they can show intensity where needed which iz pretty important.

Its interesting cuz its intense and their are a lot of good looking actors/actresses that you might be interested in.

the good looking people
