the film start beautifully with a montage of old picture and film of the childhood of the character coincide with a song by bill callahan that really fit the mood of the begin scene . paddy play an incredible cool head ex military freak that would stall anyone in their shoe . great image of terror when he arrive to vandalise in a gas mask . the drug scene be well do ( come from experience ) and the hatred and cruelty in this film be well portray . the character really make you hate them and and you feel good about the revenge that be take upon them . the revenge plot of the film be a bit heavy side until you come to understand the actual event of the past through the 8mm black and white scene . great british film . i recommend it highly if you aren not too squeamish about violence .
