Harry Brown is about an old guy who likes doing old guy things...walking in the park, playing chess, and talking about the good ol' days with his friend. He lives in an area with your typical English punks: bad dental hygiene and worse attitudes. Drug dealing and violence runs rampant, which has made everyone in area fearful for their safety.
Harry's wife was in a coma and on his way to visit her in the hospital, he has to take the long way, due to his fear of the gangs. Before he gets there, she dies. After Harry's BFF gets killed by some of the gang members, he's had enough. He resorts to his former military hero background and goes vigilante style on them, without a Batman mask. The movie has a decent story line, has good action and it's always fun to watch loud-mouthed Brits get beat up by an old man.
