Added it to my list. I really liked Forgotten (2017). Parasite and Squid Game are good but there’s a lot of other good Korean cinema out there.

It’s planned but I don’t know if it’s even started filming yet. So yes, Netflix has already commissioned more.

Iirc there’s a second season but it’s still in the works. Check out the squid game competition show, it’s a fun watch, don’t hesitate to fast forward past some parts if they don’t interest you. Like all competition shows they have their slow character moments and some are just a bore.
