It's definitely overrated. Good dark, depressive movie, but nothing more.

Rating: 6/10 (9 January 2017)

Sci-Fi ?! - not even in a bit. Why this film even have this tag?
Thriller?? - doubtfully, yupp there is violence, but there is no "trill" it doesn't keeps you in a tension.
If you want to see some depressive film - that maybe your choice. You will be allowed to smile, or feel some warm feelings only several times that may be counted with fingers on the one hand.
I'm analyze this film from the point of view of the mere watcher. When I want to watch movie, I may pursue several things: relax, joy, maybe it gives me an non ordinary thought or insight, or at least will resonate with my own views.
So of course no relax or joy, because it's really dark film, so thoughts and compatibility of views left?
As for me none of original thoughts. All ideas are swallow, even psychological aspects weak and not consistent (real people will not act in the way heroes does), the only way it may resonate with your feelings is if you know with your own eyes troubles of the refugees. In that case it'll only amplify your aggression and(or) despair (more like the second).
It have great pictures, great atmosphere (in decadent sense, of course), but does it worth it, if only resolve of acquired experience is to commit suicide?
