Narrative ReviewWhen you hear the name Vince Vaughn, you expect laughter. That seems to be the rule now. Sure, for a while he attempted drama with a "Psycho" remake, "Clay Pigeons" and "Return to Paradise," but the public spoke with their wallets. None of those films made much money, and Vaughn returned to comedy with huge hits such as "Wedding Crashers." So who better than Vaughn to lead us through 30 cities in 30 days with four stand-up comedians? "Vince Vaughn's Wild West Comedy Show: 30 Days and 30 Nights, Hollywood to the Heartland" is supposed to be a raucous ride of laughter, but it's thin on one important aspect: the jokes. Vaughn is joined by four stand-up comedians (Ahmed Ahmed, John Caparulo, Bret Ernst and Sebastian Maniscalco)
