Just finished it and will go see part 2.

I gave it an 8 for the potential, but a more accurate rating would be a 7/10. The plot has potential and I hope season 2 will do better than this but I have many doubts...

What makes is not so great in my opinion(every complain is about the production):
• short and rushed: they tried to squeeze as much as they could as far as feelings and plot setting goes and because of that they failed to do something awesome
- this covers that awkward feeling I got from the characters too since they couldn't be developed/presented properly and some of their interactions are also "awkward-cringey" not in a good way
- some "buffer scenes" that usually prepare the viewer to get into the right mood/feeling are missing so it feels like one of those episode short stories where they transition in the middle of it and it makes you lose focus about what is currently happening/lets you thinking about what happened in the last scene/waiting for something more even thought there may be nothing(long story short: bad transitions)
• bad scene cuts that simply feel like a slap in the middle of something that feels interesting(even in some fight scenes, but there it might be because of the cgi/budget/ not enough filmed scenes or well thought before shooting)
• half of the fight scenes are mediocre because they tried too much to emphasize the supernatural movements and are simply "meh" (illogical, felt awkward in some places, bad scene cut/transitions/positions after a "high speed action")
• plot holes: yeah, I know it's a drama and also fantasy, but there are scenes(too many considering how short it is) in which the action taken by a character makes you wanna scream "really?" (best example would be last episode when the priest turns away and prays....REALLY???? IN THAT SITUATION??? Which screenwriter and/or producer is this dumb to make that scene so cringe and illogical? There was no reason, no emotion, no logic, not anything that would make that action have a meaning. Please watch the scene before commenting about my comment about it.).
There are multiple scenes like this and it simply screams at how this whole project feels like a homework that was well thought
and planned, forgotten and made half an hour before the class starts.

I won't say any specific details because it would be a spoiler. I want this to be read by everyone and to know what they are getting from this kdrama and that is a failed potential top rated kdrama.

Acting - felt ok, but again, because of the rushed storytelling they didn't have a chance to trully shine
Soundtrack - decent, but nothing great. Would have loved an epic theme song to be done for this like moorim school had or ar least a better work done in some scene where a better soundtrack would've made them feel even better

It is decent overall, but mediocre and I'm sad because it had a great potential.

Worth watching if you wanna see something fast and without getting attached to the characters/story.
