Writers Salvatore Cardoni and Brian Rawlins bring some technological complications to the survival movie with “Unseen,” which follows the panic of a gas station employee asked to help a nearly blind woman manage an escape attempt from her abusive ex-boyfriend over the phone. Director Yoko Okumura crafts a somewhat frenetic viewing experience, which offers a few hits of comic book-style escalation while trying to take the central crisis seriously. It’s a tonal challenge the helmer mostly lands, doing especially well with leads Midori Francis and Jolene Purdy, who supply excellent performances as frightened strangers, helping to secure a full sense of anxiety and humanity while the screenplay works to complicate a bizarre partnership. “Unseen” is a wild ride at times, finding its way with a unique take on video call assistance, reaching a few heights of fear and friendship during the mad dash to safety.
