The good, aesthetic, nice fight scenes

The bad?
Non believable skinny girl vs not only muscled men, 10s of men but also weaponed men
It wouldn’t have hurt them to add more characters even female and let her have her own set of comrades and not just a teen
The story was flat, no connection to any character no sympathy and super detached

Also extremely misogynist, not only were women the toys and victims of these drug dealers, but if this was a man saving the day, he’d have been feared, praised, respected but they kept calling her crazy btch, satanic btch, not taken seriously, and overreacting??? Dude does anyone ever call a revenge driven male lead as “overreacting”?
“Aw dude why are you killing us you’re so overreacting”
did anyone ever say that to ma dong suk?
And worst of all “spoiler”, near his death bed and he says she was fat? Fat? Really? He murders someone and goes “ah man she was so fat I thought she lied about being a ballerina”, and I mean like what fat? She was a walking twig

kim mu yeol is everywhere yet he’s always such a generic character with no impact
