DVD review: Fish Tank

Andrea Arnold's uncompromising ­second feature film, which has more in common with her Oscar-winning short film Wasp (included with the DVD) than her feature debut, Red Road. Debutant Katie Jarvis is in virtually every scene as the elder daughter of a feckless mother in an Essex tower block. It's the vulnerability in Jarvis that is so impressive, the almost-suppressed pleasure she can't help showing when she gets a ­little encouragement from Mum's new ­boyfriend, the versatile Michael ­Fassbender. This is Wasp writ large, and as good as you'd hope.
