I didn't want to drop this. I had every intention of going back and completing it. But after being stuck at ep 11 for literal months, I just couldn't get myself to go back.

The performances are superb. I really like the mythos/world/world-building of the story. It has a great atmospheric feeling during the more fantastical elements. I love both of the main characters and can really empathize with them. I'm not interested in the love triangle between the three secondary leads, but that's not really important enough for me to drop a drama. And I didn't find the rules of the universe confusing at all.

I just couldn't connect with the story. I really wanted to see the female lead more cut up about having to leave her loves ones, because I know I would be an absolute wreck if this sort of thing happened to me. And as much as I liked the romance, I found some of the leads motivations to not be very strong, and some of their choices frustrating.

I don't think this is a completely worthless drama. The right audience would love it. It's not a drama about the role of god or the mysteries of the universe or building an immersive fantasy world (although I think it does mostly succeed on that last point). The fantastical, other-worldly elements are there to serve the romance and the drama's underlying themes: sadness, loneliness, losing hope and then finding someone in the midst of it all. And that's what this drama is really about. Finding someone to be there with you at your lowest points. Which is definitely something a lot of viewers would enjoy.
