Basically this is Death Wish warmed over, and in England. Sub-human young people terrorize a housing development (which I think they call “Council flats” over there) until elderly ex-marine Michael Caine has finally had enough and starts to kick some butt. Parts of it are good, but it eventually degenerates into a mad riot that I didn’t believe for a moment. Emily Mortimer is given a thankless part as a police detective who suspects Harry is killing the neighborhood scum, and there are some attempts at a political message, but in the end the only thing good is the absolutely reliable pleasure of watching Michael Caine work. He’s great, even in a bad movie.
