I am in love with Shin Sung Rok. Not only is he photogenic, he is a darn good actor, the best supporting actor to grab or almost grab the lead actor's shine.
I have watched 3 of his series, gonna watch the 4th that is The King's Face and in each of the 3 series I've watched, You Who Came From Another Star, Liar Game and Trot Lovers/Lovers Of Music, he has given a different performance each time or in K-drama speak, a different good feeling each time. He may look somewhat same, depending on level of slimness, but his performance has been hugely different. From the all out socio-psychopath that is borderline comical and yet scary in You Who Came From Another Star to a disturbed man that you somewhat feel a sense of pity for in Liar Game to the all out forgetful, lovable but ultimately wise President of a music company in Trot Lovers, I have never quite seen an actor displayed such vast differences in 3 roles in the space of 4 to 5 years. I read in The King's Face he will be another villain and from the little I've seen, he will definitely bring his A game as he always did. He is one actor that you can't say is pigeonhold into a particular mold.
