David Fincher sure knows his way around serial killers.
Se7en is summed up best by the simple IMDb description. Any additional information would reveal too much of the story and spoil a few surprises. The concept is a great one even before the films execution. Seven individuals who exemplify each of the seven deadly sins: pride, greed, lust, envy, gluttony, wrath and sloth; are targets of a serial killer. Except they don't just end up dead. They have an example made of them.
A word of warning - the film is gruesome. Seven murders with deaths worthy of the appropriate deadly sin.
Freeman and Pitt are both great. Gwyneth Paltrow is fine enough. The film is a bit dark (visually) for many scenes. Some of it builds suspense, some of it is just annoying. Also it seems to be raining for almost the whole film, bringing the feel down with an almost annoyingly dreary atmosphere.
Comparable to Zodiac.
