3- The K2: story all over the place, blatant product placement, some scenes were taking forever and I couldn't stand the female mc.
2- The Heirs: no story, I think producers put their whole budget on actors and probably forgot to hire a writter.
1- Blood: I'm still angry at that ending, even now. I won't explain why because I want to avoid spoilers for the poor souls who still want to watch it.
