I'm not sure how to rate this show without watching the 2nd season, but overall, the first 18 episodes were good. The world building, the characters, the complexity of the story, it was all good, even tho we can't ignore the plot armor, but that's just a usual thing in fantasy shows.

It was kind of disappointing that Eun Seom and Tan Ya didn't meat in this season, but at least she knows that he's alive. Tan Ya's arc was probably the best, her character developed the most.

There were some parts where the story didn't really make sense, and sometimes it felt like I'm watching filler episodes. The power struggle between Ta Gon, Sa Ya, Tae Al Ha and the others were interesting, but I felt the writers didn't have the courage to take some drastic measures. I also think that Eun Seom remained the same naive guy till the end. Sure, he's strong and smart, but I hope in the next season he's not gonna be this sunshine and rainbow guy who thinks everything can be solved with kindness. I mean, the message is good, but that's not how the real world works.

My biggest problem is that in season 2, Song Joong Ki and Kim Ji Won are no longer there. I don't know why, probably scheduling conflicts, but it's already a negative for me. Even tho, I like both of the new actors who play these roles.

I think the creators messed it up a bit with doing the new season 4 years later.

The OST and the Score were amazing, just like the cinematography and the VFX.

I highly recommend this show to every fantasy lover, especially if the 2nd season is good too.
