Mirror of the Witch is a mediocre drama. The story line is interesting and different, but it is written in circles. Some of the story is riveting, while other parts I felt were just more of the same. The production and cinematography is appealing. Also, the age difference between the leads didn't mean a thing. I probably would not have rated it as high if the lead female character was not awesome. She is written so well as smart and strong which is great to see. Although I get why it ended the way it did because it makes since for her character, it was still bitter sweet. I felt like it was a waste considering how much struggle the other characters put into keeping that from happening. I guess I would have rated it higher if the ending had been different also. The acting is good. Kim Sae Ron is a great little actress and I hope that she can keep that skill into adult hood. I enjoyed her portrayal of Yeon Hee with both vulnerability and strength. Yoon Shi Yoon also did a good job as Heo Jun. He had the most character development and he was a cool character. The other actors were ok also. The music is good. I won't rewatch this. If you like supernatural historical dramas or a Yoon Shi Yoon fan, then this isn't a bad watch.
