Is there such a thing as a perfect film? One that knows what it wants to achieve and does it, flawlessly, artfully and intelligently? If so, then ‘Jaws’ is as good a candidate as any. Thirty-seven years on (and reissued in a new HD print), this tale of an island community terrorised by a killer shark still feels timeless and terrifying. The characterisation is precise and acutely observed (it’s one of the great guys-on-a-mission flicks), the dialogue is witty and wise, and the plot fits together like a finely crafted watch. The performances – not just leads, but the kids, townsfolk and the grief-stricken mother too – are impeccable. Best of all is Steven Spielberg’s direction: the camera moves like a predatory animal, gliding eerily across the surface of the vast Atlantic, creating sequences of almost unbearable suspense (never mind that the scariest scene was shot in a swimming pool). It’s no wonder a generation of holidaymakers still thinks twice before stepping into the water.
