I just had a chance to see this film and I really enjoyed it. From the description of the plot, I was expecting a typical violent film. This surprised me by being subtle and realistic, with no glorification of violence. I find myself thinking about the characters and wanting to see it again.
Overall an excellent cast, though I did wish we could see their faces a little more clearly at times, or in close up. The film has its style, but I wanted to connect a little more with the characters.
The script did a nice job of maintaining tension even though the outcome felt inevitable. I recommend it.
