Overrated actors:
1. So much yes to Lee Min Ho. I cannot hate him due to his visual (LOL), but his acting skill is blaaah and he always play similar boring role.
2. Several idol turned actor, such as Cha Eun Woo, Rowoon, Ong Seung Woo, etc. Not every idol turned actor is bad
3. Hwang In Yeop. He still has few dramas (I watched Tale of Nokdu, 18 Again, and True Beauty), but I think his acting skill is mediocre. Hence I dont understand why he is so hyped.
4. Nam Joo Hyuk, dont know why I am so bored watching his dramas.
5. Sung Hoon, I think he is quite similar to Lee Min Ho, but less popular than him.
6. Ji Chang Wook, he was great with his old dramas, but his acting in the recent dramas (Melting Me Softly, Lovestruck in the City, and Backstreet Rookie) are boring.
Lee Do Hyun, Na In Woo and Ahn Hyo Seop has potential, their acting skill is getting better, especially Ahn Hyo Seop on the Lovers of the Red Sky (maybe because the influence of Kim Yoo Jung as the female lead). However, those three actors could be in my future list if they do not challenge themselves to take different image in the characters they play. For example, I am quite disappointed with Hyo Seop's decision to take role in his nearest future romcom drama (Office Blind Date) where he will play a character as handsome CEO. He already several times had roles as really handsome guy, so it is so disappointing why he does not challenge himself to take new role after being so great in Lovers in The Red Sky. Such a waste to his potential acting skill.
The same thing with Lee Do Hyun, he is now well-known with his specialty to play role as student that has relationship with older woman. Still looking forward to the next dramas of Na In Woo.
Underrated actors:
1. Oh Jung Se (he is not as handsome as the young actor, but OMG he is so versatile in every character he plays)
2. Kwak Dong Yeon
3. Im Si Wan
4. Yang Se Jong
5. Kim Min Jae
Overrated actresses:
1. Hwang Jung Eum, no debate, agree to other arguments.
2. Park Min Young, agree
to the statement that she is trying so hard to be pretty which makes her acting so unnatural and fake (but she was good at Sungkyunkwan Scandal)
3. Im Soo Hyang, Shin Se Kyung, Go Ara, Park Gyu Young, Kim Sejeong, and Lee Sung Kyung. They are pretty, but I feel there is something wrong with the characters they play in their dramas.
Underrated actresses:
1. Shin Hye Sun (OMG she is so versatile)
2. Lee Se Young (she started as child actress and she is versatile, but unfortunately quite underrated)
3. Moon Chae Won
4. Han So Hee (but gladly she is getting popular right now)
