A prohibition is a law, no? I’m gonna ask a lot of Koreans about the rating system today. Hopefully other forum users will too and report back what was learned.
Those movies have to be shown late at night when kids should be asleep. Maybe the most objectionable bits like nudity will be censored out if shown on television?
Not allowed means not allowed. The movie theater ticket seller is not permitted to sell a ticket to a Korean under 19 for a 19+ movie. That’d be illegal. Joker got a 15+ rating in Korea. Parasite got a 15+ rating.
The Korean says it's inappropriate, not prohibited. It's on a streaming channel, there is no way they could enforce a ban, even if they wanted, in a free society like Korea.
Wikiwand.com says: 19세 이상 시청가Children under 19 are prohibited from watching this programme/film.
This programme is prohibited for children under the age of 19. (이 프로그램은 19세 미만의 청소년이 시청하기에 부적절한 프로그램입니다)as translations.
All it says is "Viewers above 19 years old." (not sure if it includes, or excludes, 19)
