Healer was a good drama. The story was solid. The female lead was strong. The male lead was hot. The directing was slick. I didn't love it, but I thought it was pretty good. If you like action romcoms with a solid couple and a heavy plot, I would recommend this.

Things I loved:
The Music: Eternal love is on my "favorites" playlist. The ost elevated the drama.
Ji Chang Wook's hotness and acting: No need for explanation.
Lack of pointless relationship drama: BLESS.
The plot: Have to admit, the plot was great.
Pacing: Timing was on.
Kisses: Those were some good kdrama kisses.
Minja: My favorite character. She was badass.
Bong Sookie/Healer: Loyal and badass. Awkward and clumsy. Suave and intelligent. Lonely but loving. Brilliant.
Villains: Clever and realistic way of showing the corruption in political circles.
Her dad: He was a really good dad. Very supportive and just.
Action sequences: THOSE WERE SO FUN!

Things I was meh about:
The Romance: I'm sorry. It just didn't make me swoon. The whole secret identity thing made it feel less authentic. I can't say more without giving spoilers.
The main lead actress and her character: Tried to make her seem relatable by giving her "quirks" but I NEVER connected with her on an emotional level. The actress's performance was flat and forced. I didn't hate her acting, but it didn't do anything for me either. She was kind of boring to watch at times. You may love her, this is just my opinion.
Moon Ho: Coward character. Lied a bunch. Even though he had his reasons for keeping secrets, they weren't good enough. Didn't like the scenes with him.
Politics: I don't like politics lol, and I got confused quite a bit so I had to rewatch certain scenes. Still, it kept me engaged. I don't blame the drama.

Overall: Really good drama. I really don't know why I didn't love it as much as others. Probably the romance and the main girl. The other aspects of it are great though. Worth watching for sure! It was still exciting and I was hardly ever bored??.
