This drama should really be called "The Journey of Jung Yi Hyun" rather than its given title since I felt like the story was mostly about him and his own personal journey though hell and back (basically). He was also the only character that really had any development or depth to him.

The other characters were just alright..Sun Ok Nam was super sweet and adorable, but for being nearly 700 years old I just expected so much more from her character. While I couldn't dislike her since she was just so nice...I didn't necessarily like her either, as she was--for lack of a better word--quite boring.

Kim Geum was so cute and lovely as a person but same thing here: he was just...flat.

THE FOLLOWING CONTAINS MAJOR SPOILERS BUT IS NECESSARY FOR THIS REVIEW:

While at first I was super happy with the idea of Kim Geum "getting the girl" in the end because it's so rare that a second lead (and let's be honest here, he had all the characteristics of a typical and stereotypical Second Lead going for him) comes out victorious in the end...so, that aspect alone was really awesome...I just ended up liking Jung Yi Hyun SO much more and I couldn't help but think of how much more romantic and moving it would have been if Sun Ok Nam truly fell in love with him in the end (plus Kim Geum and Sun Ok Nam had like ZERO chemistry...boo).

I just felt SO bad for our dear Professor. Sun Ok Nam came out of nowhere, TOTALLY lead him on, and then left him just like that as soon as she realized he wasn't her husband. She made him think she really cared about him and would always be there for him and then...POOF! Whoops! Wrong guy.

Damn.

So...anyway, I don't think this drama has much going for it other than it's fairy-tail-like elements, which I always enjoy in Korean dramas since they are not as common. The CGI was God-awful though, so you kind of have to cringe your way though and just accept things.

Overall it's a decent enough watch for a rainy day, just don't expect to get a lot out of it.
