Overall, I think this drama is a must watch. The story is intriguing, there are plenty of twists and layers in the characters. The pacing sometimes felt a bit slow for my liking, but I still enjoyed the drama on the whole anyway.

Now, some elements of the show felt repetitive, like the monster of the week kind of feel. I personally like the framing of the story, and how the twist came into play. Though gotta say there were quite a few twists and by the end of it you're sort of expecting more twists are just going to come into play.

Anyway, I think the drama is well presented and it was definitely worth watching if you like the genre, though I personally wish there are more action.

My personal favourite is Eul Tae, there are so many layers to this character, which brings me to my next point...

***SPOILER***

I wish there are more build to Eul Tae's backstory, because it felt underplayed and that he didn't get enough build up on why he became the way he was, and why he was so obsessed with Hwal.

The ending was heartwarming, and it ties the big plot points, but I do question why they met again when it was established that Bulgasals don't reincarnate. I know it's nice to have a happy ending, but I feel this invalidate Hwal's sacrifice, and that why this happens requires an explanation. Also, if Hwal reincarnates, does that mean Eul Tae did too? It was Eul Tae's soul to begin with anyway.
