“Gold” (*** out of four) was a superficial but entertaining story of a down-on-his-luck prospector (Mathew McConaughey) who teams up with an eager geologist to discover gold in the ruins of Indonesia and the various ups-and-downs they go through after becoming millionaires. McConaughey’s usual dynamic performance makes all the difference and makes this story worth watching, even though it (by now) tells a familiar story of the rise and fall of American business and greed. Bryce Dallas Howard makes another strong showing as his supportive wife.
