Retired ex-serviceman old dude Harry Brown (Michael Caine) doles out his own brand of justice after his best friend is killed by wild younglings.
Kinda exactly what you think it'll be. Caine is good at what he does. And it has an underused Emily Mortimer in the flick.
Pretty much a neither here nor there movie. It's good as movies go, acted well, technically good as well, but not groundbreaking nor exactly a new story. I liked it, but it's easily forgettable. Not saying it's a movie to avoid, it's worth watching if it happens to be available, but life would be complete without seeing it. I do appreciate it wasn't bombastically unrealistic.
