Abdel Raouf Dafri's story is excellent, the description of life in prison very accurate and realistic. Tahar Rahim, Niels Arestrup, Reda Kateb, and the whole rest of the cast of actors, everyone is perfect here.
I did like (Jacques) Audiard a lot, now I consider him as one of the finest directors in french cinema. His use of slow motions, and of partly blinded frames is both aesthetically and metaphorically justified (absolutely exceptional !). Only a genius could make the most intense and beautiful film with only images of a brutal and ugly world, such as life in and out of jail. Except for very few seconds of images showing an airplane's wing above the clouds, and, later, waves on a sandbeach, there are hardly any shots of something _not dull or ugly_ in 155 minutes. And yet I fell in love with every single second of this entire movie.
I've seen it 4 times in theatres, and invited myself 4 people to watch it with me. I now urge you to see it if you haven't yet !
