as a person that reading the webtoon, i was actually disappointed with this, cause they change the story after the episode 4 and imo it doesn't make the story looks good, i was waiting for the beauty monster and it turns out not showing, and for the monster protein it actually not die like that on the webtoon, and i dont really like that they change the personality from the actual characters, and it seems that they not really telling about the main character, they even adding a new characters that actually there is no in the webtoon. also i waited for the epic part from the webtoon when the girl playing bass to make the monster going to her so she can save the other member group, but again the end of the story was change, and they didn't talk about what making them being a monster, however in the webtoon was tell about that.
but for the cgi and the acting were pretty good i still can accept that, this is actually not on my expectations as a person that really excited from the webtoon, maybe if someone that not read the webtoon would say this was so good
