An extremely odd serial-killer exercise, all the more so for being the directorial debut of regular-guy actor Bill Paxton (Titanic, Twister). Paxton also stars as a father who teaches his two young boys to murder people he believes to be demons, a bizarre tale told in flashback by one of the grown boys (Matthew McConaughey). As the horror elements mount, it becomes clear that it would have taken a stronger directorial vision than Paxton possesses to make such loopiness work.
