Southbound is thankfully cinematic and well-acted.

Here’s how it unfolds: Through the soothing sounds of a radio DJ (voiced in velvet and sandpaper by Larry Fessenden), we learn of a place that lies just south of here. It’s a small town in the middle of nowhere consisting of a gas station, a diner, a hospital, and a few derelict structures that can’t be identified at a glance. There are some neighborhoods, too, but believe me: You wouldn’t want to live there. Or die there, which is what most people do.
