Jun Ji Hyun, Gong Hyo Jin, Kim Go Eun, were all so flat with their acting. Also, why is Baekhyun getting praise for his performance in Scarlet Heart? He was totally unnatural and tended to act like a little kid.
I never had a problem with Lee Jong Suk or Kim So Hyun, I always thought they were amazing in their roles
The first one that came to mind was Lee min ho. I loved city hunter but didn't care for him anywhere else. First female to come to mind...Gong hyo jin, I think she chose decent dramas and did okay but why do people love her?? She is okay at best and normally its the plot that keeps my attention in her dramas.
Sometime Idol actors get too much credit like Yoona in K2 or TOP, but there are plenty of good idol actors that I have loved and might even call them actor-actors now.
Hwang Jung Eum- her face expressions, her voice (she should not really do narrations, it sounds like she's reading off from a script), and her inability to have romantic chemistry with her male leads.
Park Shin Hye- I've seen her since stairway to heaven, thought she was good. But her popularity grew faster than her acting skill.
Lee Min Ho- I don't know, maybe it was because his popularity is so big yet I find nothing special about his acting.
Lee Jong Suk- He seem to act like himself, and I don't really like that. All his characters seemed like one person with the same attitude and mannerism. I find myself not wanting to see him in a drama that I'm anticipating for, but the roles seem to always go to him like Pinocchio, W, Doctor Stranger, and While I was Sleeping.
Yoo Ah In: good actor. It's just my opinion that when I see him in a role, I imagine someone else that could have matched the character. I think it's his face and build.
others: Jang Geun Suk, Nam Goong Min, Yoon Eun Hye
and i dont think lee joon gi is overhyped at all because all his characters are really good and some are really exceptional if you ever saw his movie you would know why he gets so much praise. even if few of his dramas are badly scripted he never disappoints
i think they are over hyped not over rated lee min ho lee jong suk kim soo hyun - even though he is a very good actor some times his crying shots feel awkward and unnatural imo park hae jin- i dont get it ok techyon singer- yes actor -no song hye kyo han hyoo joo park shin hye acting in movies is really good than in dramas may be she always gets offered such roles baek hyun not that he was bad in fact the character he is supposed to play is chidish, ignorant little foolish and later on his character matures its the same as how it was presented in chinese version but the praise he gets is a little too much i guess due to exo gong yoo-some times he seems really excellent and some time does not really connect to me
