David Fincher’s Seven (A-) is relentless in its sustained somber tone as two detectives – Brad Pitt and Morgan Freeman – track down a serial killer inspired by the “Seven Deadly Sins.” Unlike typical buddy cop movies, there’s no room for levity or comic relief as the central duo plumbs the depths of depravity and faces their own demons in a grim, rainy, unnamed metropolis. It is handsomely crafted, extremely suspenseful and disturbing.
