This is the best movie I saw in the 21st Century. It starts slowly, kind of Donbass in the USA, naturally adding all the attributes - refugee camps, torture, dead bodies, murderous nationalist nuts ("What kind of American are you?" is an equivalent of "Whoes Crimea is?" in modern Ukraine). Finally the intensity increases reaching climax.
Being half-Ukrainian / half-Russian I am particularly impressed by the movie’s reference to the “extraction” of Azov leaders from Azovstal to a neutral territory.
