Nowadays, there are many idol members who are venturing into acting. Some are okay some does fail but there are those who stand out.
First on the list is Im Siwan. Siwan was a member of Star Empire's boy group Ze:A. Now, Ze:A was fairly famous, however, not for their songs but because of Kwang Hee in variety shows. Then Siwan went into acting and the group was surviving. He was praised for his acting skills in the movie "The Attorney" and TvN's "Misaeng". Siwan won the Excellence Award in acting at the 4th APAN Star Awards for his performance, as well as Best New Actor awards at the 9th Cable TV Broadcasting Awards and 51st Baeksang Arts Awards.
Siwan's acting is, for me, very refined. He is very natural with it. He also looks great in front of the camera and the camera loves his face. Watch some of his cuts from "Misaeng"
Next is DO. Now, EXO's DO is indeed a great actor. For his performance in "It's Okay, That's Love", D.O. was nominated for the Best New Actor and Male TV Popularity awards at the 51st Baeksang Arts Awards. In 2015, it was revealed that D.O. was ranked number one by critics among 40 idol-actors who participated in dramas in 2014. He is now starring in movie with Jo Jung Suk and Park Shin Hye for movie "Hyung".
Now, there are rumors that he will leave EXO but I hope that won't happen because his voice is as amazing as his acting skills to not use it. When acting, DO fits the role of persons with mental disorder or a very serious person. I do hope he tries a different character to show his versatility.

Last one is the latest idol actor who received praises for his acting. B1A4's Jin Young has been acting since 2014 but was only acknowledge this year for his role in "Love in the Moonlight". He is more known before as B1A4's leader and composer.
