Radius (2017)

Radius takes one of those instantly gripping “what if?” ideas and turns it into a lean, nerve-tight thriller that keeps tightening the screws the more you learn. With its amnesia-stricken lead and a trail of eerie, pale-eyed deaths, the film plays like a grounded sci-fi nightmare—quiet roads, small-town dread, and a mystery that unfolds through unsettling discoveries rather than flashy spectacle. Diego Klattenhoff anchors the tension with a haunted, human performance, and the story’s shifting understanding of who these people are and what’s happening makes it hard to stop watching. It’s not for viewers who need big-budget polish or who shy away from frequent profanity and abrupt violence, but if you like smart, concept-driven horror with a satisfying, perspective-altering payoff, Radius is a terrific ride.

Radius is clearly aiming for a tight, high-concept thriller: one man, one deadly rule, and a mystery that tries to turn a simple premise into a moral dilemma. The hook is genuinely strong and the early “what is happening?” tension works, but the film can’t always sell its big ideas—limited resources show on-screen, and some performances land a bit stiff, which undercuts the dread and emotional weight. If you need polished production, sharp dialogue, or horror that escalates with spectacle, this will likely feel like a clever short stretched to feature length. If you’re patient with indie rough edges and mainly want an eerie concept to chew on, it’s still an interesting, occasionally gripping watch.
