This is one of my favourite dramas ever. It's amazing. I think the only reason why some people drop it or are put off of it is because it's long. But, in my opinion, every episode is amazing. The acting is amazing, the characters are great, the plot twists keep you engaged and the ost is beautiful. The most amazing thing is the costumes, the outfits are so spectacular that it makes costumes in other historical dramas look tacky. I've watched this drama three times and every time I notice new details. I've never found another drama that's impressed me as much as this one.
