I've been watching asian dramas since I was a kid :D :D I have the advantage of being an Asian kid in Asia so :P
I like Japanese drama the most. I'm not much of a fan of their love stories except Hana Yori Dango and some few others. I love J-dorama for its family-theme and crime/investigation/mystery. They're really good.
I like Taiwan dramas. Especially rom-com. Nah, only rom-com. The humor is really well.... humorous. :D
My kind of funny :>
As for K-drama, I watch them occasionally. They have this good, creative foundation to a story, but almost always lost my interest in the middle of it. Tear-jerkers are pretty good though. I prefer the historical dramas over modern ones.
