Healer is... mediocre.

Now, it's possible I'm not the target audience. And it's possible I expected more from this series than it promised. That being said, I dont think I've ever been this disappointed in a series before.

The plot is solid. Cute romance, intriguing mystery. Cool.
However, it is so horribly stretched out. 20 hours for something that could have been 5. It seems the writers put in absolutely every scene they wanted to, without ever considering if they drove the story forwards. It means that moments that should be dramatic end up losing all of their significance, because with 10 hours left of the show you get the feeling it's all going to be irrelevant. And it means that while the series is technically a "thriller", you feel about as much thrill as going 10 km/h at a highway.

As for the "action" element, these scenes were hugely disappointing as well. The use of stunt men during parkour and fight scenes was so jarring that I was genuinely laughing out loud. Don't worry, though, there are only about 5 fight scenes in the entire show, though the main character does do a lot of unnecessary parkour.

Add to that possibly the worst soundtrack I have ever heard in my life. What felt like less than 5 songs were played at seemingly every opportunity, until they were grating at my ears. Thus, even the important scenes related to the (solid) plot were ruined for me.

There are good things to this show (after all, I did finish it). But the negatives for me weigh up to something that I cannot justify giving anything above 6.

That being said, go watch it. You'll probably love it.
