I have to agree with HAVA and others that have said that KHJ's acting was better in PK. I also agree that new actors try to hide their bad acting skills behind the cold and arrogant act, however imo you still need to know how to act those emotions to do good acting, hence why we know they are hiding behind them. hehe. It might be easier to some actors because they think that being cold does not require much facial expression, but coldness its all in the eyes and expressing emotions through your eyes alone is the hardest thing to do. Example KHJ in BOV, his character was cold and not very expressive yet he wasnt very good at acting it. I have seen ISWAK anime several times, and I think KHJ portrayed the charcter well. He was better in his acting. If you have seen him in WGM, he was very shy at the beginning, then he loosen up a little at the end. I think he is getting the point that actors cannot be bashful in acting, they have to be up for anything. I dont know anybody else on that list.
