If you like a film that is Michael Caine being a pensioner who's wife dies and then his best mate gets killed by some YOUTHS, who then decides to get all medieval on their asses, and it has Emily Mortimer as a thoroughly unconvincing detective inspector, and it's all GRITTY, and URBAN, and the score gets on your nerves for being heavy handed, and the whole thing is very well-executed, but the more you think about it, the more it feels like 'Daily Mail : The Movie' because, you know, all YOUTHS are BAD, and therefore it's OKAY if you KILL them, then you'll probably like 'Harry Brown', cos that's sort of what it is.
