What could have been a sniggering excoriation of the 1 percent is instead given a touch of emotional weight in this documentary about a billionaire couple's quest to build the largest private home in America. When the real estate bubble bursts and the economic crisis looms, the dream home construction grinds to a halt. Instead of making the ridiculous couple at the center of it all targets of scorn, the filmmakers turn them into quintessentially American poster children for living beyond one's means. It's got a certain reality show flair to it, but it's a credible and relatable look at today's mega-materialistic culture. 100 minutes PG.
