My Demon did a really good job of being what it is: a fantasy romance. It is imperfect, but it has far more ups than downs, even considering the bizarrely implausible nonsensical demise/non-demise of a main character.

My biggest kudos go to FL Kim You Jung. Some actors act the role, others inhabit the role. Kim You Jung crawled into the character of Do Do Hee and gave it everything. She is marvelously expressive, every character emotion perfectly timed and absolutely believable.

Kim Tae Hoon was icily malevolent as Noh Suk Min. He deserved a more sensible wrap up for his character.

Kim Hae Sook is so so so good as Joo Chun Sook. She's one of my favorite character actors and must be everyone else's favorite too because she's in EVERYTHING. And she's so wonderful she needs to keep being in EVERYTHING.

The fantasy was well conceived and executed, thanks in part to atmospheric shot composition and cinematography. The romance between the leads was smoking. They were adorable together. I could have done without the early episodes' tryst with the Enemies to Lovers trope, but it resolved quickly, if not quite quickly enough for me.

I don't usually have the patience to track multiple character development arcs, but I got invested in each one in My Demon. Script writer Choi Ah Il did a wonderful job wrapping them all up after taking exactly the time it needed to do them justice.
