I watch everything and I go between phases of chinese, japanese, and korean xD
...but Lee Jun Ki, oh you hot, sexy...@____@;;
Korean dramas are great (coffee prince was goooood!!) but they tend to get emo, fast. If it's not findng out that your gf is your sister or the person you love who loves someone else who loves someone pretending to be a man who loves you has a terminal disease...there's always something else. There are a few that are good all the way, but I can't think of it off the top of my head.
Japanese dramas are cute too, though sometimes overexaggerated. I remember my first drama was 'To Heart' with Kyoko Fukada. Shame that it's hard to find good looking male actors in those dramas tho (like Gokusen) :[
Hong Kong dramas are long. My god, they are looooooooooooooong. I really liked that one drama...'My date with a vampire' or something like that. Taiwan dramas are also cute, but also overdramatized and a lot of them tend to focus too much on mushy stuff. I love the martial art/epic dramas like 古代 stuff...forgot how to say that in english. Though I think if a chinese drama is good, they tend to get dragged out so the producers can make more monies and then it goes downhill :\ much like 還珠格格 =__=
