Over the course of 5 years since I first knew Lee Min Ho from Boys Over Flowers, he has excelled greatly in acting. The most obvious improvement started from City Hunter when I first noticed he has the ability to emote and convey the emotional changes with his eyes. He has beautiful eyes and this really does become one of his best asset when he uses it to express emotions. He pushes and challenges his boundaries even further when he took on the role of Choi Young in Faith.
Choi Young is written to be a stoic character so this really put Lee Min Ho to the test and challenges him to fully utilize his eyes and facial expression to emote and deliver the emotions across to the viewers. If you think he emote very well in City Hunter, he up the notch by another level in Faith
