Se7en

Detectives Somerset and Mills investigate a series of murders in a dark, perpetually rainy city, where each victim embodies one of the seven deadly sins. The seasoned Somerset—days away from retirement—shows the impulsive Mills how the world works when monsters know Latin and plan meticulously. David Fincher crafted the most stylish and nihilistic serial killer film of 1990s cinema, complete with a final twist the audience never forgets.

Seven is the most sophisticated serial killer thriller of 1990s cinema. Fincher, Morgan Freeman, and Brad Pitt in perfect sync. The ending is one of the most disturbing and memorable in the history of the genre.
