I can guarantee right off the bat that Healer has all the traits that most viewers love and want to watch in a kdrama. Action sequence executed by a gorgeous looking male lead, beautiful romance, amazing chemistry between the leads, enchanting comedic reliefs and a very well written story. If this drama didn't appeal to some people, it's obvious they're looking for something different and a different drama may be able to deliver that for them. I read that some people also say that the many flashbacks to the past were the weakest points of this story execution, but I didn't find it that way because the transition between the past and the present story are done so well when you are patient enough with the material. The rushed ending could've devastated some people as well but as an overall experience, Healer was an exceptionally well-written piece of a small screen art because each episode ended with a suspense and the thrill of each episode is also very high.

Ji Chang Wook became my immediate actor crush after this drama because it's obvious how good of an actor he is. This was his third work that I watched after Fabricated City and Suspicious Partner, before I moved on to The K2. He is obviously in his best element under these types of action roles, and Park Min Young played really well for her character as well. Yoo Ji Tae was an absolute delight to look at, but I did find his facial expressions a bit stiff in a sense. The ahjumma hacker was the real MVP of the show I must admit, since she's so unapologetically sassy and badass, haha.

The producers could've been more creative with the BGM as the same song was used so many times, but I really loved the OST that Ji Chang Wook himself sang.

Rewatch value is very high because it's such an enjoyable ride to be able to revisit some action or romance scenes, and this drama has also now been uploaded in full series in KBS World TV Youtube channel. Go watch it if you haven't!
