Here’s an utterly gripping thriller; a masterclass in thought provoking suspense, which tells the story of a damaged man who discovers that the killer of his parents is being released from prison early and goes in search of revenge. 

But after a brilliant 20 minutes, Blue Ruin has not only covered but largely overturned the ground on which most revenge thrillers would expend their entire running time. 

What follows is the fallout from those actions, with age-old eye-for-an-eye riffs suddenly made to seem fresh and new by a film-maker crucially more interested in exploring what happens next.
