Kati with an I

Over the course of three tumultuous days, Kati a teenage girl in Alabama has to confront big life choices over love, family and her future. As Kati’s half-brother, director Robert Greene gains an intimacy that makes viewers feel part of the family, reminiscent of last year’s award-winning doc “October Country.” Cinematographer Sean Price Williams (“Beetle Queen Conquers Tokyo”) vividly renders this passage from youth to adulthood.
