Before he tackled the Zodiac Killer, David Fincher’s breakout 1995 film was concerned with another serial killer. In a corrupt, perpetually wet, and crime-riddled city, old-timer Detective Lieutenant William Somerset is paired up with newbie cop David Mills to investigate a series of murders that seems to be based on the seven deadly sins. The result has become a cult classic, a sticky, visceral ride with an ending that’ll knock you sideways.
