“Riot Girls” (** out of four) was an awkwardly done thriller set in an alternate 1995 in which two gangs (Madison Iseman, Jenny Raven, and others) are pitted against one another in a war for territory, resources, and survival after a mysterious disease has killed all of the adults leaving only the young to roam the wasteland. Mostly a collection of ideas done before and done better in other movies although it’s fast-moving enough to be watchable. Perhaps it’s time to stop these futuristic melodramas because the future just ain’t what it used to be.
