The movie has been produced masterfully. It is beautifully shot. Cinematography makes you feel claustrophobic and on the edge, same with background score. Screenplay is amazing as all the action starts and plays out very unexpectedly.
Action scenes are done better than any action movie I have seen recently. Weapons feel actually impactful. Bullets sound like thunder and destroy things they hit leaving gaping holes in walls etc and knocking air out of people with Kevlar. Also, not much gore is shown but blood and disturbing scenes are plenty.
Story is very interesting if you are a fan of thriller genre.
My only complaint is that the "independent contractors" are shown to be unrealistically ruthless and good at combat(as if they have plot armor against enemies and the law).
