The drama didn't do that well in ratings so I had pretty low expectations going in. But once I picked it up, I was definitely surprised. The drama was super addicting and has became one of my all time favorite Kdramas. The story was great with an excellent mix of action, and romance (wouldn't mind more of that). It was very well executed, and gave me the feeling that the story line was really thought out and the writer had everything planned, unlike some dramas where you feel like its been dragged out or rushed. The characters also felt well developed. Although most dramas might have one or two characters that annoy me, I didn't actually feel like I hated any of Healer's, which I attribute to a combination of great writing and acting. I loved the casting choices with the drama, especially Ji Chang Wook. I hadn't noticed him too much before, but I absolutely fell in love with him with this drama! His performance was amazing and he simply just owned his character. Whether it be the action involved with 'Healer', or the adorable 'Bong Soo', JCW really captivated my heart with his acting. Park Min Young was great as well, the leads made me love both of their characters so much and the chemistry between them was so strong. I loved the romance that played out and the cuteness in that. But beyond the leads, all the supporting characters were great as well, which made the drama much more touching since you could really feel for the characters.
