A gripping if thoroughly unpleasant film. Beautiful visuals,steady pacing, assured unshowy acting.You get so involved with the juvenile characters that the thought occurs that a sound thrashing might have deterred some of them from what they, ultimately, get up too. Jack Gleeson has grown up near me here in Dublin and a pleasanter kid you could not meet, which makes his role all the more shocking. His ability to play too camera is unnervingly good. Awesome stuff.
