As a very angry alcoholic police inspector with a troubled teenage son, who finds himself investigating the disappearance of another teenage boy, Vincent Cassel is terrifically good in Erick Zonca's first-class policier "Black Tide". The material may not be particularly original but the handling is splendid. In this case, the devil's in the detail; this is a brilliantly written, directed and acted film. You might say it's even old-fashioned and what's wrong with that when it's coupled with this degree of intelligence, (it's even got a couple of nice twists). For once, a thriller well worth seeking out.
