Next month marks 2 1/2 years since I watched the first episode of a Korean Drama with my wife. Amazingly, we still like (some of) them. You can see our favorites near the top of my Korean Drama page.
When we started, we watched every episode of each KDrama we started. During the past year we've watched only a few episodes of an increasing number of dramas. (For a list of those series, scroll to the bottom of the KDrama page mentioned above.) Is it because we're raising our personal standards? ... or is it because the KDramas aren't as good as they used to be? ... Maybe a little of both. (Who knows?)
