This is an example of what and how "mediocre" really is. I love the actors, it is just that, the story was such a mess. It started out as a strong drama with a lot of potential. Imagine a present (hot chic) doctor will be dragged by someone to time travel back to Yuan dynasty's time? The idea is fresh and unique to me for it is the first time-traveling drama that I have seen. But when it reached the 10+ episodes, it became so boring to me for many reasons. Repetitive conflicts, mediocre acting, and really absurd antagonists. Even the story itself didn't make sense (I am trying not to spoil anything, if there is really to spoil about). I have this hope that the ending will be something different, but it was really a disappointment. If there is something which got me in this drama, it's the music. The OSTs are really good. That's all on the good side. To wrap it all, Faith is not that bad but obviously, is not a good drama. It can make you skip a lot of episodes and proceed to watching immediately the ending. I hope to see Lee Min Ho and Kim Hee Sun together again (if there will be a chance) for they really have a good chemistry, but not with a time-traveling story. Better go with a rom-com.
