Chinese dramas are so notorious with this it frustrates me very much! Do you happen to know more exceptions to these besides Eternal Love??? Thank you!
The modern Cdramas usually have happier endings, but by "happy", I just mean that most of the main characters make it to the end of the drama alive. Wuxia and historical dramas are the ones that usually have endings that make you want to set your hair on fire. All of them, however, because of their length, are repetitious and get bogged down badly in the middle, but even Kdramas can suck in the middle.
I refuse to watch a Cdrama while it's still airing, or before it's completely subbed. Then I can read here at MyDramalist about whether it has a happy ending or not, and I avoid the experience of watching a 50 hour Cdrama that will never be subbed after episode 40 something because the subber got bored or had other commitments.
