Since almost everything has already been said about Healer, I will try to keep this review as short as possible :
So, basically, you need to watch this drama. Right now.
Well, I'm not saying this is a perfect tv-show (slow motion effect abuse, too much emphasis on obvious things...)
But it's really enjoyable... mostly because there's something to see, to hear and to feel for everyone in this drama.
So... basically, you need to watch this drama.
