Story:
I recently completed it and first I would like to stare my experience with you. the start was very good. A light cheesy comedy in fantasy genre to fill up my time. it as around episode 6-7 when it started to get boring. For some reason the script writers decided to focus on this power struggle of good/ evil which kinda ruined it for me. Remberary/ yeon woo cant catch a break. he is constantly fighting against devil's schemes and there isn't much time left for singing, dancing, practicing and other idol problems which made the comedy part in the first place. This drama started the first episode a very funny and hilarious start, even the fantasy part was like a part of a fantasy game.

Honestly at first I was really excited to start this because of Kim Minkyu but this show was such a drag. Episodes were so hard to get through because they never seemed to have a clear goal or whatever the goal was it was poorly executed. I understand that this is a fantasy drama however Idol storyline of the male lead becomes too unrealistic.
When I watched The Heavenly Idol I saw nothing but the land of missed opportunities. It looks like the creators don't have the concept of the world they're making, no wonder the worldbuilding contradicts itself all the time.

Chemistry and Acting:
It was very funny to see Rembrary become an idol. The acting was very good. The female lead did a great job too. The romance was cute! But the romance was very, very underwhelming. I don't feel like the leads had any chemistry at all, especially considering Kim Min-Gue's previous role in Business Proposal and how dynamic his chemistry was with that actress. The acting was well-done but they couldn't help what they had to work with. Wild Animal's members should had have more time to develop their characters to make the story stronger and I'd like to have the chance to see more cute moments between the main couple. Their chemistry tries to rise along the drama but fails to fully bloom.
