Frankly, I'm not sure how to mince this one, since there's quite a lot of things to cover and explain why the ratings are as they are. Story's likable, it has sufficient amount of plot twists that will make you interested enough to watch every episode. It, however, has a few rather naive explanations for the later buildup and will seem a well-cooked, but messily decorated dish. Acting made me immersed into the plot straight away from first episode; there's mild chemistry between the leads but NO awkwardness, which is to compliment, since there's ten years of age difference between them. Moreover, Ryu Deok Hwan and Park Se Young were adorable in their roles, especially their on-scene relationship. The baddies have done considerably well too, and I especially put accent on General's army bunch, since they gave me that tiny bit of amusement I needed to go through whole 24 episodes. The music was good, it was tailored to the scenes and not overly high-pitched and bothersome. Commendable. I am torn when it comes to rewatching aspect. Mainly, it's because while I did love the story, acting and the numerous paths that the plot took, the second time around it will be extensively less interesting since the suspense of plot resolve will just not be there anymore. And that takes a huge slice of attractiveness about it. This is a well-crafted drama, that's plainly obvious. From the plot, actors to musical background, the flow was impressive and welcome. However, there are a few problems I'd like to point out; such as too many episodes (it should've had around 18 at most), skyrocketing angst that piled up in the second part to the point where it was nearly unbearable (maybe it's gonna be a plus for other reviewers, but I found it to be way over the top), and the weak resolve at the end. I did understand what they were going for, but it sounded so loopholed that it barely passed as a viable answer. Without further ado, I recommend Faith as a worthy sample of historical romantic tale.
