im not sure how to describe this, but the best word i can find is "nothing".

Story :
so the story basically the mc trying to stop the "game" once and for all, but somehow endedup inside of it. i mean mc knew best that the game wont stop as long as there is a "client" that sponsors the game. so why ? why get in the game ? there are no guarantee that the "client" is on the island. in the end, the game ended up in a riot between players and staffs. why raise the weapon ? he knew the plan busted so bail out with as much people as possible is top priority. like mc doesnt even know what is he doing anymore, nothing changes, history repeated itself.

and the characters is pretty shite, hard to remember. i'll try my best at least with the "main roles":
-Mc : i dont think the mc knew what he is doing.
-The cop : what is he even doing ?. you are a cop, you work with evidence. you got plenty recruiter corpse, mr.kim corpse, soldiers corpse. why is he a cop in the first place if he cant see this ?
-Player no.230 : the joker of the game, special role yet pretty much got nohing, i cant see he barely can act.
-Player no.120 : got decent character, well your typical woke representative. somehow an allrounder that can do everything that makes me think he(she? they?) plays mc, however the biggest hypocrite in the series. playing heroes risking people life just because you want to cut your pp ? what a joke.
-the other players that on the main role list : why are they even considered main role ? some had some backgrounds but too insignificant. its okay for supporting but main role ?, is it becaus of the poster ?.
-Guard girl : decent character, but at wrong series. if i were the writer i would have keep this one as mc for a spin-off story as the guard pov
*special note : the recruiter has no significant story yet damn the actor is good, short but so memorable.

Acting :
the panicking player on the first game acting is awkward, toilet battle is awkward, im pretty sure the night riot is awkward too but the blinking lights saved it. my acting score is purely for the mc and recruiter russian roulette, just for that scene its worth high score. that was freaking good

Music :
that theme song, come on its a sequel know its iconic but atleast it should be rearranged or remixed or anything. and for the first game why flymetothemoon ? i believe there are a lot of old korean song that would fit better, arirang alone for example if it could be rearranged into a deadly vibe song it would be so cool.

and nah doubt will ever rewatch this, or even unless you got somehow fomo about it dont even start. the only factor of rewatching this is how good s3 is, yet even if its good still likely wont rewatch this

overall :
nothing in it, no story development no good character. not a thing just a hype thing. oh just 1 good thing, the picture pretty good they took the shot nicely or at least some of it does. not worth much of a try but well. thumbs up for the promotion team good job really, since this series is popular lets go milk this franchise until its dried out
