Michael Caine is way too good for this movie. A lesser actor giving a less powerful performance would have allowed this film to be dismissable as merely cliched and sensationalistic . Ugly too. But Caine's mastery of his craft lends the film a gravitas it doesn't deserve. Caine is brilliant. Every moment he's onscreen he is utterly riveting. He even makes the ludicrous journey that his character is required to take from lonely, vulnerable old man to tough and fearless killer seem somehow plausible. But it isn't plausible. There are many moments when the suspension of disbelief required is simply too much. An old man with emphysema could not have withstood the kind of punishment that Caine's character suffers.
All that said. I enjoyed his performance so much that I can recommend the film simply for that. Also, if you like a good baddie (which I surely do), Sean Harris's performance as the unspeakably evil Stretch - your friendly local dealer in guns, drugs and underage girls - is lip-smackingly good. I know actors; he must have had SUCH a good time putting that characterisation together.
But the central premise is essentially fascistic: what teenage thugs need is not better education and the prospect of a proper job doing something useful, no, what they need is to be brutally murdered by an old age pensioner. OK? Got it? Good.
