The original challenge here

30 films from 30 different countries, in the hope, to watch more, follow the tags

UPD 15.03 - Rwandan "Father's Day" (missed the opportunity to watch) and Algerian "Houria" (the screening was canceled) were replaced with "Peacock Lament" from Sri-Lanka and "Borders" from Burkina-Faso

UPD 28.03 - Mexican "Dos crímenes" replaced with "The Criminal Life of Archibaldo de la Cruz" (the first surprisingly turned out to be unavailable with English subtitles).
Syrian "The Extras" was replaced with "Berbu" (decided to use a chance to watch a Syrian film at an online film festival to use it for the challenge).
