The time stamp announces that this is the future; that it’s also a dystopia is evident from the regressive image of James’s wife, Mary (Lena Headey), fussing about in a skirt and heels like a 1950s television handmaid. James, meanwhile, plays the caring father, sitting down to supper with his family (dinner, and then the show) in a scene with his children, Charlie (Max Burkholder), and Zoey (Adelaide Kane), that establishes his loving paterfamilias bona fides. 
 
There’s a distinct, daddy-knows-best whiff to this tableau that’s underscored when a TV announcer bleats about the New Founding Fathers, God and America just before the Emergency Broadcast System kicks in. James mans the alarms and the gates roll down, securing the windows and doors as if home were a prison.
That’s the unsubtle message, or rather just one of several such blunt, bludgeoning ideas that the writer and director James DeMonaco tucks into “The Purge.” 

Some introductory text suggests the political stakes, however blurred: unemployment is at 1 percent, crime is nearly nonexistent and it’s Morning in America (again): cue the smiling faces, fluttering flags and some pacifying notes from Debussy’s “Clair de Lune.” The movie doesn’t directly point fingers at political conservatives, but Mr. DeMonaco deploys the satire about God ’n’ Guns with such cumulative heavy handedness, that the target, so to speak, becomes obvious. (The emblem of the New Founding Fathers looks a lot like one for the National Rifle Association, complete with a gun-toting eagle.)

The message just gets louder and louder, cruder and cruder, which is too bad because Mr. DeMonaco knows how to set a stage. The banality of James and Mary’s milieu initially brings to mind the opening of Jackson’s “Lottery” (1948), in which the ritual bloodletting (ostensibly for harvest) is compared to civic activities like “square dances, the teenage club, the Halloween program.”

Once lockdown commences, however, Mr. DeMonaco quickly loses his grip on the ever-more blood-slicked material. Out come the guns and in come the villains, inner and outer. A symbol of collective callousness emerges in the form of a sacrificial black man (Edwin Hodge as the Bloody Stranger), an 

Everyman lifted wholesale from George A. Romero’s “Night of the Living Dead” if without the powerhouse effect.
“The Purge” is rated R (Under 17 requires accompanying parent or adult guardian). Wholesale slaughter.
