This is British cinema at its best. Michael Caine plays Harry Brown; a widowed ex-marine, who lives alone on one of South London's sink estates and keeps himself to himself. One day his one and only friend is murdered by the feral youths who run the estate and something in Harry snaps. He says early on that his military life was locked away and forgotten when he met his late wife and now it comes back with a vengeance as he seeks justice in his own way. Caine is outstanding as Harry Brown and portrays perfectly the hopelessness and loneliness of so many old people in this country today. No punches are pulled in displaying the futility of life on this estates either. Having worked in places like this it was very familiar and discomforting. When you watch this film in the comfort of your comfy living room remember that thousands of people live like this. This film doesn't glamourise violence and gun play in the way of so many American films but shows the desperate lengths that the hero goes to for justice when the police can't or won't get it for him. When Harry Brown gets a gun its because he sees the enemy has them, not because its a natural thing for him to do. If Caine doesn't get at least an Oscar nomination for this then there ain't no justice there either.
