DVD: I Saw The Devil (18)

I Saw the Devil is a revenge thriller in extremis. It follows a secret agent (Kim Soo-hyeon) as he plots an elaborate and brutally violent reprisal for the serial killer who murdered his pregnant girlfriend.

He sets about constructing a cat-and-mouse game normally involving the mutilation of one of the deranged killer's body parts, yet even the best laid plans can go horribly wrong. The film is stylishly directed by Kim Ji-woon, whose work includes A Tale of Two Sisters, and Min-sik Choi stands out as the killer. Yet the stylised sexual – some might say misogynist – violence leaves a bad taste in the mouth, and there is little of any substance underpinning the rather thin plot.
