One definitely has to adopt maximum suspension of disbelief for Squid Games. I found the first season so ridiculous I barely made it through. Really? They kept this entire industrial island a secret? None of the masked drones quit and blabbed after living in solitary confinement?
Then again. It is Koreawood. They do enjoy their histrionics.
Ever hear of a certain D.C. area pizzeria?
You can also have a murder in the White House and have it almost completely covered up thanx to a cooperative media so keeping such an island a secret is not a big stretch.
You can also assassinate a President in broad daylight and, despite all the evidence indicating a conspiracy, have it covered up by having the as the lead investigator the very person who put together the assassination conspiracy. So, again, keeping a Squid Games island a secret is no great stretch. Anybody making such allegations could be written off as a “conspiracy theorist.”
