I don't like to drop dramas because I want to finish what I started. But If I find something unwatchable I just delete it from my list and I think of it as if I never watched it (for example On the Way to the Airport, I couldn't stand it, I watched just an episode, and then I dropped it). But if I find dramas that in some ways are interesting, but at the same time are boring at moment, I just keep watching (if I couldn't stand them, I just start another thing, and sometimes watch a couple of episodes of them). For example The Journey of Flower, I found it strange, and I couldn't understand well the story or the characters. After about 20 episodes - I don't remember well when - I started to love it with all my soul. The same for Six Flying Dragons, at first I didn't understand the story - because I didn't know Korean history - then after 15 episodes I started to love it. However there are cases such as for the K2 o Faith - in which I found very hard to finish them, but in the end I finished them without love or like them neither a while. Everyone has his/her personal tastes. Now I know what I like and what not, so now I do start only what I think I might like :D
