I agree with Delinnia. The Korean audience should not be picking on one actor's performance alone. A production of a drama is a group effort. The screen writer & the director have the responsibilities to stick to their story & not swayed by the audience. They also have the responsibility to their cast members.
I read in a website that the Japanese dramas & movies are gaining more popularity in South Korea over their own dramas & movies. The Korean audience should patronize their own people because their actors worked very hard for their domestic audience. Where's their loyalty. Air City's rating was not that bad at all compared to some the new dramas they're airing right now which only have one figure ratings. Air City had 2 figure ratings except for one episode.
???? nobody is perfect whether you're senior or junior. Ji Woo is just as human as anybody else. Some dramas or movies "click " some don't depending on the type of story the audience wanted. Ji Woo worked hard on this drama, please give her some respect. Ji Woo don't let anybody spoil or ruin your joy. God bless you always.
