Master of the Mask is like a roller coaster ride, the story takes you up to intensity, then drag you down with regret and suddenly knocks you off to happiness. To sum things up, the plot is not perfect at all, it has a high and low point. The cinematography is superb for the historical setting and because it's an all-star cast, this show was favored and impossible not to watch.
The finale was tied up neatly and will give you an approving look while witnessing our main lead achieved his dreams and hopes. Just bear some loopholes for certain episodes, but in the end, you would never regret of watching it.
