Hip hop’s finest double-act, Dr Dre and Snoop Dogg, pay loose, improvisational homage to the 1976 comedy classic Car Wash with this amiably inert tale of two roommates scheming, scamming and “busting suds” at the local LA ‘wash. There’s a kidnapping subplot, consistent casual misogyny, and cameos from Ludacris, Eminem and Tommy Chong. Overall, patchy, but not entirely pointless.
