Mr. Byrne - relying almost entirely on a doom-metal soundtrack, game performers and a grungy palette of oily browns and moldy greens - somehow whips his ingredients into an improbably taut man-versus-Satan showdown.
What makes "The Devil's Candy" a standout is how well-developed these characters are. This is ultimately a movie about parenting, and how even "hip" moms and dads fear the choices they make are hurting their young.
The film moves so quickly that lingering tonal unease from scene to scene never really has time to stick, and little plot questions only start nagging after the last screaming lick over the end credits fades.
Byrne's artful use of image and sound takes the narrative to a whole new level. Heavy metal music dominates the soundtrack, as well as the characters' lives, providing an ideal conduit for the demonic forces lurking beneath the story's surface.
