In the 2000s, it became customary to cast popular K-pop idols in dramas. Initially, this generated mixed reactions. Their appearance had provoked predominantly negative reactions outside their fandom because singers and dancers acting outside of their musical circle was regarded as unprofessional. Also, some idols were criticized for poor acting. Nowadays, this has become much more common feature in Korean dramas, as the public has been getting more used to the concept of "idol actors" and some idols have become known for their excellent acting skills. Their critical reception is still mixed, however, some of them, like Bae Suzy, IU, Seo In-guk and Im Yoon-ah, became successful as actors and actresses.
