I like how calling Pan's Labyrinth "El laberinto del fauno" is supposed to make it seem more ~exotic~ and ~foreign~.
Also, every movie you named is either pretty highly acclaimed in the mainstream West or pretty popular among teenagers on tumblr.
Also, some of those movies are really bad.
They were trying to name some movies that people who usually aren't interested in foreign films might like. The only film they listed I do not like is Battle Royale. Either way, who gives a damn if the movies are acclaimed in the mainstream? The mainstream gets it right quite a bit. It isn't like the tag automatically means the film is bad.
