i remember spending I think over a hundred chapters reading nonstop, eager to get to the good bit where the exorcist girl (who showed signs of noticing the discrepancy between his real self and his concept) and the theatre troop kid (who was said to have the potential to at least fight back against woojin's monstorous acting) actually stole the show, but they ended up having extremely minor roles and basically played no part at all. Remove them from the story and everything stays the same.

like when they pit the movies in the book against actual real life box office records

the time he played howl's moving castle for the va's child or when he used sign language on stage to talk to a deaf child fan and it brings a genuine smile to my face. The exorcist movie screening where his real life friends' jaws' drop at his incredible talent, the inadvertently funny profiler hanryang after filming talk show, the time when he is cast as an extra and his acting has gotten so good that even without the system/script/cheats his smile looks so genuine that the cast is floored, the glimpses of his relationship with his parents and sister.

he might have one conversation in English and suddenly you have people in the upper echelons of the entertainment sphere talking about the multiple foreign countries he must've grown up in or his extensive background at multiple acting academies abroad (spoiler alert = he was a korean graphic designer until 5 months ago who had never been outside the country!).

this poor guy finally have the confidence to be himself and get immediately ignored by the entire world. Just as the public were coming around to his true self, Miley just has to ruin it - what do you mean his genuine smile looks just like the joker's so he's acting??? Why did everyone agree???? So for his entire career, nobody will know to treat him like a real person??? He wins an oscar and this is the thanks he gets!!?? God its giving me a migraine just thinking about it. The fact that he continues bearing his heart out during the speech, unaware that public perception has already deemed everything he's saying fake makes it hurt all the more. Just more proof for me that the later chapters aren't nearly as good as the earlier ones.

For example, stating that the level of acting in Japan is subpar or lacking. I'm not a huge fan of movies so I don't know anything about the level of acting in Japan. But as of right now this just seems cringe to say.

MC getting tired from the shooting of the Drama or movie, solved by resting in the blackspace. Any potential controversy surrounding the MC just gets solved within the next 2 chapters by the characters around the him.

Plot holes: Where did the MC get his ability from? What did the shaman mean when they said the MC is possessed? What is the identity of the MC's ability, who is voicing the system, why did he of all people get this ability?

Missed opportunities/Weird Openers: Besides the initial information that the MC was blackout drunk on the day he got his abilities, without expanding on how, or why, or where, or who, or what gave him the abilities.

The introduction of the shaman character and their daughter without, any real interaction with them. Seriously these characters were the closest we got to discerning anything about the MC's ability, yet they were discarded.

The introduction of the potential rival/competitor character. There was a new character that was introduced for the production of Beneficial Evil. The 2nd Choi Nana work. This character was apparently the exact opposite to MC and possessed great talent for acting. A chance for a rival/competitor/potential villain, nope. This character was thrown out and became an afterthought after the filming of 'Beneficial Evil'. In fact, I don't even remember this character being mentioned during the filming of 'Beneficial Evil'.
