In my opinion as a black individual, people are overreacting about the blackface. The character did it as a disguise blend into a tree background, watch it carefully you'll see. It blew my mind to also see real black people in there, unless their blackface was hella realistic which i highly doubt. Otherwise great movie, its comedy but its not like break your ribs funny. It has its moments; the actions pretty good, the acting is superb and the storyline is very satisfying which deserves a great rating in my book. I'm very new to this "sageuk" genre and see myself getting more into it.
