This film is like the French film "French Blood" http://www.imdb.com/title/tt4168502/ The acting is very professional, straight forward and not over acted which happens in lots of films with violence. Both of these films shows what happens when there is too much of energy, anger and no thoughts how to live life as human until something happens that makes the changes.
The film shows well the conflict that arises after one has had enough of all that idiotic ideology and how difficult it is to break the old ways, they keep haunting in the background all the time. Both films are extremely good drama and I would say these are a must to watch especially for all those who think they have all the answers but no idea what to do.
