The story centers around Detectives Mills (Brad Pitt) and Somerset (Morgan Freeman) as they investigate a trail of murders. The crime scenes are always very strange and seem to resemble one of the seven deadly sins. With these clues, the detectives track down the real killer but he gets away in a gripping chase. Throughout the sequences, Mills and Somerset build on the relationship between one another and there are some heart warming moments to balance out the horrifying ones. Eventually, the killer reveals himself to the police covered in blood. Can the two detectives survive the killer's final trap? I won't spoil the ending but it is definitely worth watching and is considered a classic in shocking endings.
Kevin Spacey plays the murder and, in my opinion, it was his greatest role in a long time. He was calm, cool, and collected which made him absolutely terrifying whenever he had something to say. You'll really learn to hate this guy quickly, and Spacey does such a good job of achieving it. The twist was good upon itself, but Kevin Spacey definitely made in ten times better.
I always end up watching this movie a few times a year to refresh myself in a deep and compelling narrative. However, I definitely won't recommend it to anyone with a weak stomach.
