This is the first Drama that has made me go through the whole range of emotions form sadness to happiness to anger to excitement to fear and so on. I actually cried on in some scenes and on others I had a lump on my throat. I have to say personally I have Not read the novel on which this is a modern take so I can only base my review on what I have seen. But in general a film version tends to fall short because of missing details etc
Going off of that I really enjoyed it and it was worth the long episodes since they are a little over an hour. I have to say that the greatest character development would be for Song O-gong the great sage equal to heaven. He turned from a selfish jerk and a nut job to a jerk and nut job who would do anything for the one he loves. I have to admit in the very first episode as soon as they showed the evil spirit i turned the whole thing off because I got scared I'm a big chicken but it was totally worth it. Especially for the kisses!
I've seen quite a few c-dramas and the kisses are always luke wam at best but here Lee Seung Gi turned up the heat and Oh Yeah Seo was Responsive!! can you believe it?! this is the most responsive female lead that I have seen and maybe this is rated MA which for me its like what ok??... it could be because Western movies that are MA you can bet you will see everything and I mean butts and boobs will be the norm but all I saw for O-gong was a shoulder hump
Since I'm not familiar with what actors are a thing now in Korea or anything I got a feeling that they had a small cast I mean there was a character that was super important and it was basically the same person that being said I really wished Richie could have had more time with PK and Jade Dragon thats love. Basically everything that happened or didn't was because of love. I'm hoping there will be a season two and if there isn't I am also good with the ending since "Whenever you are scared, distressed or in danger call me and I will come"
