Devil's Knot

Egoyan (Next of Kin) directs a movie about three boys in a small southern town who are murdered by a group of Satanic worshippers. Firth (Magic in the Moonlight) plays a PI trying to make sure the accused don't get the death penalty.  Witherspoon (Mud) plays the mother of one of the boys. Nivola (Selma) plays one of the boys fathers. A lot of the cast is recognizable. Still, it drags. All in all, I say: SKIP IT
