In my mind, a foreign language film can go one or two ways.
Either the film can be so ingrained into a country’s culture that it would not work anywhere else, or the film can be so universal that it could be told virtually in any language or country. I personally try for the middle ground, where a movie shows characters that are relatable to any nationality or race, and no other live action foreign language film has impacted me in that way this century more so than 2011’s Iranian film, A Separation.
Nothing else to say
