This really could've been a good fantasy/supernatural/romance drama. The overall story, its background and the creatures were more or less fairly interesting, original and entertaining. The elements were all there, the actors are talented and well-picked for their roles, and the production value was quality. There was only one thing that really made all that hard work and effort veer sideways and that's the structure, pacing and plot points of the story itself. How it was written, the timing on revealing important information, etc.

The only thing that I think is something that should be said to anyone who is thinking about watching this drama, beware, you'll only get your answers to all your questions and pondering until the very last episode. Typically, you'd think this would be ok because, most of the time, that's how stories are structured, more or less. But the writer of this drama, did not organize or plan their drama out very well. Here's why....

Unfortunately, the writer to this drama thought that keeping all the important information of the 'how' and 'why' to the characters actions, their motivation, and basically their entire history until the very very end, was a good idea. Spoiler, it wasn't. Every question that the audience asks, every theory the audience ever theorizes, every thought about the characters they've had are all abolished in one jammed packed episode which shows the revealing history and why of it all. This will often leave a very bad and unsatisfied taste in the audience's mouth because the payoff is too short-lived. The reveal is too sudden. The emotions are left to stir without giving enough time to feel a sense of resolution after the high.

Another mistake the writer made was the way they left clues in the episodes leading up to it. When you leave clues, it should be like building blocks. One stacked on top of the other. Clues should give more information but leave with a question. Expanding upon one another, creating a path and leading towards a direction but just not knowing where its leading to or what's at the end.

Unfortunately, this writer decided that they should leave their audience confused and grasping at straws to connect two dots. All the clues in this drama felt like random puzzle pieces that were all different colors, different shapes and different sizes. Never feeling like any of them fit together or would fit together. Every clue that was left just left more questions and felt like you weren't making any progress in trying to figure out or understanding what had happened and what was happening. When you continue to make the audience struggle to figure things out, then you leave them pretty exasperated and annoyed towards the end until they come to the big reveal and then they are left feeling frustrated and unsatisfied.

The decisions this writer made were all the wrong ones and this severely diminished the overall drama itself and really dropped the quality of it after the fact. Honestly, its a shame because this had good promise until the story started dragging its feet and then info-dumping until the very last episode to reveal everything.
