Hello, Kind of a newbie here. I have watched a lot of international films and shows over the years. I am from the US and I really liked French movies a lot. But once I found Kdrama's I haven't gone back.
I'm going to answer a bit out of order, if you don't mind.
1) I started watching Kdrama's when I started working on another website that streamed movies and shows. We didn't host any of the shows, we just provided, by embedding, links to shows. Viki wasn't one of the websites we could provide links to but we did use Viki as a reference sometimes to find the proper show that was requested. A few of those requests sounded interesting so I watched a couple. I started with I Am Not a Robot, Sketch, Are You Human Too? and like them well enough that I kept coming back while still watching other shows. But once I saw The K2, Healer, What's Wrong With Secretary Kim and a couple of others, I was hooked.
2) Addiction? I can't say what I am suffering from is an "addiction" because I feel it is so much more than that. I have a computer hooked up to every TV in my house and there is at least one on Viki and a couple of other sites 24/7. The one in my bedroom is always on all night and I watch up until I fall asleep and if I wake up and there is nothing playing, I either finish what I was watching or find another program to watch.
3) I have tried to go back and watch all of my saved American programs that I used to watch religiously, but I just can't seem to get into them at all anymore. When I do try to watch one I find I am just to bored with it and end up coming back to Kdrama's.
4) What draws me to Kdrama's? French drama's depend a lot on sex. American dramas seem to depend on shock value, violence, nudity and sex to capture your attention. Kdrama's don't need any of those kind of gratuitous, superfluous tricks. Kdrama's use human emotion to draw in their viewers and only use whatever else is needed when it's needed, such as violence or sex to tell the story. With the possible exception of What's Wrong With Secretary Kim and that bedroom scene...whew. But even that depended on suggestions and innuendo. It was not explicit at all, at least not on screen. What happens in your own mind stays in your own mind.
5) Will I give up Kdrama's in the future? Only if certain conditions are met.
....a.) If I die. and
....b.) if my 4 TV husbands, Ji Chang Wook, Park Seo Joon, Lee Jong Suk and/or Kim Hyun Joong disappear and suitable replacements are not found in my heart and mind. (Although I doubt you'd ever find suitable replacements for Wookie and Sukki)
(Goodness, after looking all of that over I just might have to start a 12 step program )
That's my story and I'm sticking to it.
