For me a great example of British film making regardless of budget. Truly well acted, raw and gritty from beginning to end. The opening scenes lead you to realise this is a violent and vengeful film. So no excuses to be offended if you watch. Can't deny the dead man shoes similarity, which by no means is a bad thing. A gripping storyline held by a strong cast. And the twist (if you like) at the end I found to fit well with the story. As Bull said he'd been to Hell!!
