A juvenile delinquent gets out of the pen and immediately embarks on a rampage of misdirected anger, most of it unleashed on an unsuspecting young woman. Shot through with the same kind of bebop bravado that Godard was experimenting with half a world away, the anarchic descent into amoral madness that is The Warped Ones (Kyonetsu no kisetsu) sounded a lost generation’s cry for help and kicked off Japan’s cinematic sixties with a bang.
