There are a couple of problems with this movie, the characters are lacking a proper backstory, the actors aren't good either, but after all it doesn't matter. Because these are minor issues in a much better story.
The most surprising thing for me was that there's no right or wrong in this movie. There are no moral winners, the director let's the story flow and it's up to the viewer to decide what to think. Another positive aspect of the film is, that it's very down to earth. It's about current social issues in Europe like immigration, ethnic tensions and radical movements based on the inability of the justice. (Maybe this would make difficult for non-European viewers to connect, but it worked for me.)
So if you're tired of movies about slavery and oversimplified topics that are way beyond us, here's a film about the world we're living in and the issues we have to deal with.
