I think the biggest downfall of this drama was that it tried too hard to be a lot of things that it just wasn't. That being said, it was still a fun, good show in your downtime. If you just take it at face value, then I think it's very easy to fall in love with this drama.

In terms of the story, we follow Rembrary, a being from another world who is known for his divine powers and ability to heal, on his quest to defeat The Evil One. In the midst of their final battle, the two of them were transported to our reality. Now, Rembrary is stuck in the body of a K-Pop idol Woo Yeon Woo, a member of the washed-up K-Pop boy group Wild Animals. While trying to figure out a way to return back to his world, he meets Kim Dal, Woo Yeon Woo's biggest fan. The show follows the two of them as they try to defeat The Evil One and save the world.

Essentially, this show tries to mirror some of the popular tropes in webtoons while also trying to mix in some popular K-drama tropes as well. This is where the show can be really hit-or-miss for people. "The Heavenly Idol" tries to mix in all sorts of concepts that may seem inconsistent or all over the place. It juggles heavy concepts like mental health and religion but also tries to be lighthearted and comedic. It tries to deliver a deep and well-thought-out story, but at the end of the day, there was too much going on that none of it really stuck.

However, I still believe that it wasn't a bad show. The messages on mental health are good messages, things that many dramas stray from talking about. They delivered backstories and motivations for all of the characters and gave a reasonably realistic depiction of life as a failing K-Pop idol. The characters all had their moments to shine. If you just watched the show and follow along with its plot, not trying to critique its every flaw and plot hole, then you can see the charm of it.
