I enjoyed watching Mirror of the witch or Secret Healer (as it is called on Netflix). I read the reviews so I was surprised when I was still watching at episode 14 and still enjoying it. Visually it is beautiful, the cast were pretty good and it is more of a historical fantasy than a romance. I loved the story as it was pretty dark in places had a few good twisted plots. I did find it annoying at times and I felt that they kept making the same mistakes over and over e.g the prison was pointless as with the exception of one or two times pretty much eveyone walked out or escaped within a few hours. There were questions left unanswered which left me feeling a bit frustrated but I loved the fact that they did give you the backstory on the Shamen. The age gap wasn't an issue for me but it would have been nice if they used an older actress and put more romance in but I did like Kim Sae-Ron and how she played her character  and I probably would watch this again in a few years time.
