This is going to be a very honest review from my perspective. I decided to write one after seeing some unrealistic/ too biased reviews for this drama. (*note that this drama was considered a commercial flop, and I will try to explain why I agree[d] below) First thing to note, is that I watched this drama for Lee Min Ho. I recognized his previous works - like Personal Taste and Boys Over Flowers - and thought I should give this show a shot. I myself hesitated to watch it, (being a historical drama and all), but it's worth watching, and something I'd recommend to Lee Min Ho fans. Now for the story itself (I'll try to keep this short), let's say that overall, it was lacking. The main problem I encountered with this series is continuity; a lot of it didn't make sense. A lot of the time I was left confused, wondering how the plot ended me up where I was. Ironically it was the main theme of time/travel that bothered me the most. In order not to spoil anything, let's simply say it had issues. The acting left something to be desired, to say the least. It wasn't bad, but I wouldn't commend the cast on their acting either. Furthermore, the relationships ... let's say, also had issues (at least for me). Music is probably the only thing I really liked in this drama. The OST played well throughout the scenes, and managed to embed certain scenes/events into my head. In closing, here's two things; i. DO watch Faith because it is a good watch for those who enjoy historical dramas and/or Lee Min Ho (and/or the other actors/actresses - whomever you favour, i guess) ii. DON'T watch Faith if you pay really close attention to the plot. Certain things will tick you off throughout the series.
