Kieslowski's title is accurate: a hideous murder is directly followed by a hideous execution; both illegal and legal acts are detailed and protracted. The film does not set out to explain the punkish young killer's motivation, but restricts the viewer to his tunnel vision from the start, with the edges of the picture sludged over and a lowering yellow light at the centre. The depiction of violence is far removed from the usual camera choreography, and is, in consequence, truly appalling. The killing of the taxi driver is achieved in amateurish instalments, and takes even longer than the famous killing in Hitchcock's Torn Curtain. Not for the squeamish.
