one random thing. i get that the very concept of the show is gonna need cgi. but jesus christ it is... sigh... it's not BAD per say, but the way it's done in this show grinds my gears. they put so much focus on it, but it's just... not it. an example of well done cgi in modern kdrama is parasyte the gray, and it also is a similar style to this show. AND THE AMOUNT OF SCREEN TIME- i swear, if you add up all the scenes that are literally just body parts getting fixed, it would be more than some of the main casts' screen time.

side note: I am not the biggest fan of Go Kyung Pyo, but maybe that's just bc i've only seen him in this and love in contract. i understand that he is playing abnormal characters/characters that express a lot of apathy and/or psycho-ness, but like- apathy is still smth that you have to act. like- you need to be able to convey emotion as an actor, and that includes for weirdos and psychos. i don't think he's fit for this type of character.

concept: loved the idea. i think more effort should've been put into lore and stuff. like i get it's supposed to have an element of mystery, but what's the point when it's only a mystery to everyone except the characters...
execution: not the worst i've seen, but i am disappointed. i had high hopes for this, but i shouldn't have knowing it came from hulu.
pacing: it's like a bumpy ride, but no major stuff. it's like the car ride to the grocery store. you already know the way, it's boring, sometimes there a pothole/plothole, etc.
