LIKED:

The Naksu who fought Park Jin as the original Mage leader S1, in very beginning who we saw soul shift into Mu-deok, is same face as FL in S2.
The animal trainers did well: Loved the turtle moments, especially with Prince Go Won and the dog that could see soul shifters also was perfect.
FX good but not as awesome as in S1.
Costumes for the most part were good.
Acting by actors and actresses well done for most of them. Lee Jae Wook was great in both S1 & 2. Season 2 Jin mu mage (Jo Jae Yoon) wasn’t as compelling, but he always gives a good performance, especially when playing the bad/evil guy.
Music was for the most part appropriate, scene building and well executed.


DISLIKED:
A lot of the issues/dislikes from S1 were continued in S2, for example: Shaking camera moments and Fx green screen noticeable.
Using same actor (Im Chul Soo) to play different, non related characters; Mage Master Lee and one of the guys delivering alcohol, that Jang Uk saves by killing soul shifter [that went into son’s body].
Pacing issues, a lot of boring parts due to bogged down by too much politics and showcasing human greed

Directing: too much staring and inactive moments, extended scenes that didn't help in any way.

Writing:
Plot issues throughout, dragging on moments that were unnecessary, forcing chemistry that had nothing solid to back up the instant connection. Confusing choices for changing the character of FL that was so well developed in first season, to a character that was lacking in all aspects and then claiming she was this all along. The mess they created for the main storyline for the supporting characters of the Royalty, Unanimous Assembly and Jin mu w/ his mages, was very lame. The body swap and soul change explanation for Naksu/Bu-yeon was badly executed. Yes they used the same body for FL S2, as the opening scenes of Naksu in S1, but that didn’t help. Too many anti-climatic or low impact moments of important characters in S2, that were so evolved and developed in season 1. The character development and especially growth even for the FL, ML and other dominant characters was non-existent.

Wardrobe: the crowns of the King & Queen, all looked like those paper things you get from a fast food burger place. Also the jewelry mostly became heavy and clunky looking (like the hair pins). I understood why the colour palette changed to be more somber for literal execution of the SHADOW concept of S2, but the effort seemed lacking.


OVERALL: Most of the reviews cover all the crappy parts of the plot and their actor/actress character preferences. With a decent budget and good FX and getting a S2 to explain the concept of the plot, why did the Hong sisters give up on their plot and create a cliche and trope driven mass of garbage? Also I am sure they could’ve afforded the best camera production crew, so no excuse for zooming in way too close (I hate seeing up actor noses, cut off faces) and no film stabilizer! To give a proper review I did watch everything again, after watching it the first time. But I did use fast forward often in S2. As seems to be the trend lately with Korean Dramas, S1 is exceptional and S2 disappoints. I hope in 2023 that changes and we get consistency. I would recommend this show overall, and I will rewatch certain moments, but not the whole thing.
