The Lonious Monk

There was the Oscar win for Parasite last year too ... almost similar themes to SG...
But I been deep into foreign language cinema (more especially from Europe) before they became hip or popular... I have loads of them dvds I copped back in the day
Yeah, wasn't there a Japanese movie called Battle Royale that had a pretty big underground buzz and had similar themes. Now that I think of it, these kinda stories are common enough in Asian cinema to basically be their own subgenre, sort of like how they really seem to love those ghost movies like the Ring and the Grudge.
