Saw it also last year at the cinema with a friend. He was bored, I was mildly interested. The film is imo very mediocre, as it tries to raise political questions through a family drama with satirical undertones, but doesn't get serious. It raises some questions for the audience, but had imo nothing to tell for anybody slightly knowledgable of the conflict. If it weren't for the "importance" of the film I don't think much attention would be given to it. The direction is mediocre at best, the actors are solid, other technical departments didn't strike me as original in any way. It's true that the film has some startling images, but for me it worked more as an idea that deserved a better movie.
I recommend it if you're interested in the topic.
