I just discovered a lot of free Korean dramas on
www.viki.com which is actually an app built into my Samsung TV. It's kind of crazy how much Korean entertainment is built into it.
I marathon-ed City Hunter a few months ago on Netflix US. It's a great series and probably the one I'd recommend to someone who hasn't watched Korean dramas before (because most of the rest are way more soap-operaish) but I was disappointed that it had nothing to do with the Japanese anime/manga of the same name that I grew up with.
Can't find any other Korean dramas that can keep my interest though. Strange that in a culture that supposedly has so many young plastic surgery starlets, it seems like the trend in dramas is plain/older looking women surrounded by pretty boys with coiffy hair. Bleeecch. Don't want to watch that.
