You could try searching with genre filters? Use "top shows" under the "shows" menu, then refine from there. For example, the top 5 rated
dramas on MDL (currently) from only thriller and action genre and from Korea
are Healer, Six Flying Dragons, Bad Guys, Two Weeks, and City Hunter.
Change genre and/or country or whatever as desired. :)
I was personally going to recommend Bad Guys as an action/thriller that I enjoyed, and there it is in the top 5, haha.
I
do like the idea of having a short list of strongly recommended dramas
for some common categories and think it might be helpful for people new
to Asian dramas, but I'm not sure how it would be implemented. Plus it
would need to be updated from time to time.
Or...rereading your
post, do you mean the viewer ratings in Korea? Or just general viewer
feedback on a given drama? Or both? I think viewer ratings would be
especially difficult to compare since they've changed so drastically
over time. Like, nowadays 10% is moderately respectable, but even 10 years ago, that would have been viewed as a pretty poor showing, haha.
Perhaps someone could put together a list of the top dramas
(by viewer ratings) by year, though?
Dramawiki has a lot of ratings,
but it would be a huge task to organize all that. And you can look at
a list of the highest rated kdramas of all time on wikipedia, but looking
at that list, there's not that much that would be all that appealing
(or even accessible) to the average international kdrama viewer (and especially someone looking for action/thriller dramas). And
since ratings are so much lower than they used to be, there are very few
shows post-2010 even on that list. Even splitting it out by year, you'll have the list dominated by weekend and daily dramas for the most part, so I don't know how useful that would even be. You'd have to go further and limit to certain timeslots to avoid that.
