This fatuous coming-of-age drama plays out like an advertisement for entitlement. Jack (Will Poulter) has a case of gap-year angst that is not helped when he meets Evelyn (Alma Jodorowsky) and her well-heeled bohemian chums (including Cara Delevingne, underused in a supporting role). A tourist in this world of privilege, Jack is fascinated, until he gets his visa revoked and financial reality bites. It’s staggeringly shallow stuff.
