Umm.... kind of like a ranking thing?
When I first got into dramas I used to watch quite a lot, but slowed down in recent years. maybe I'm falling out of love with tv? Out of the dramas, even if I did not watch the whole thing I've seen about 90% of it so I'll put it on. (Most probably I haven't seen the last episode - I'm the type who finds most jdrama finales to be boring :\)
Not a complete list at all; I'll add more when I can remember them ;)
