Serial killers and mismatched cops overcoming antagonism are seldom fresh, fruitful subjects for movies, but this exceptionally nasty thriller blends genres to grim and gripping effect...The film's world is so shadowy, decaying and intentionally dated that one often wonders whether anyone involved has heard of electricity; at the same time, however, Somerset and Mills' slow voyage from claustrophobic murk into blinding light makes for a vivid dramatic metaphor. Moreover, Fincher handles the violence with sensitivity, announcing its obscenity in spoken analyses and briefly glimpsed post mortem shots, but never showing the murderous acts themselves.
