This is a totally original Kdrama that doesn't follow the usual formula (except for the knowing each other as kids bit)!
The main theme music seems a bit of a mismatch for the action and is calm & easygoing while the cool action scenes are playing out but somehow it works and is instantly recognisable as the Healer tune.
Ji Chang-wook & Park Min-young as the leads look so young! They get my vote for the most adorable, cutest couple ever to grace the small screen. When I watch them I think...ahhh that's what love is really like! I have to say I love Ms Jo (AKA Kim Mi-kyung) this has to be my favourite character I have ever seen her play (and she's played a lot)! Every character is beautifully acted and incorporated fully into the storyline, This is the secret to every successful drama. There is a sort of docu-edgy cool feel to the drama. It really is impeccably written. There are some really memorable scenes and great dialogue which demonstrate how creative the team were behind this. The last 2 episodes veer off into another direction, but it does not distract from the overall arc.
