"I guess the challenge is more "filmed abroad" than "set in another country"
I just saw this. I was using Crash Landing on You (saw The Package as it aired and remember someone saying a lot of it has to be set in another country so I didn't do Chocolate for that category since only a little bit is in Greece). Crash Landing is over half set in North Korea and some set (and filmed) in Switzerland as well, but I have no clue how much was filmed on the Mongolia set (whether it was just the scenes of the border/fields or if the village was set up in a Mongolian area, no idea, only that they did go there) etc; in other words, I am not sure which really cold place was so cold they had to delay! :)
If I don't see another to trade it with, can I just keep it since the "set in another country" for me was like the other mentioned-the way Hollywood can film in Cali no matter where they are saying the story took place. The filmed abroad tag isn't widespread yet (cause few if any but hardcore fans of a particular show know unless it's specifically in a place you just KNOW isn't Korea like the Switzerland scenes in it. I also wonder if the filmed abroad tag would possibly be used for things LIKE Chocolate that have a 5-10% abroad filming amount and skew the results a lot.
It's all a big human endeavor, and language is among the messiest parts of our endeavor! :D
