Southbound is that rarest of creatures: a satisfying horror anthology film. Produced by Roxanne Benjamin, it has eight credited writers and four directors — one of whom, Radio Silence, is four guys — but a geographical continuity allowsSouthboundto hold together as a cohesive experience in a way that Benjamin's V/H/S anthology series did not. In Radio Silence's "The Way Out," a pair of bloodied men speed along a highway to escape skeletal wraiths on their tail; in Roxanne Benjamin's "Siren," a touring band runs afoul of a very strange desert family; the high point, David Bruckner's claustrophobic and grisly "Accident," follows a very average man as he attempts to save the life of a woman he ran over; in Patrick Horvath's "Jailbreak," a less average man attempts to free his sister from a cult; and a home invasion gone wrong in Radio Silence's "The Way In" serves as a prequel to "The Way Out."The dusty southwestern locales give the picture a Rob Zombie/John Carpenter vibe, while Wendigo director Larry Fessenden as an unseen DJ bridging the stories makes Southbound a sort of Twilight Zone: The Movie for the modern era, but one that can actually answer that all-important question: Do you want to see something really scary? And you should.
