Higher: Moon Lovers. Scarlet Heart. I gave it a 10 compared to your 8.5 I thought that the cinematography was beautiful and the story was well paced. Liked the romance, the intrigue and the historical part of it.
Lower: Twenty. I gave it an 8 instead of 9. It was good, but just not that innovative.
It was kind of hard to choose because we haven't watched many of the same dramas ;)
