Mom (Brenda Blethyn) is near death liposuction gone wrong. Her once promising daughter (Catherine Keener) is working in a one-hour photo shop. Another (Emily Mortimer) is an actress with career-threatening body-image issues. An adopted child (Raven Goodwin) is overweight, black and simmering with disaffection. Would you call the Marks family depressed or obsessed? Either is putting it mildly. But there's also something funny and truthful about their glum, strongly acted pursuit of hopeless dreams. This feels the way a lot of us are living now on desperation's dull yet still cutting edge.
