“White Boy Rick” (** out of four) was an overly familiar, predictable true story of Richard Wershe, Jr. (Richie Merritt) aka “White Boy Rick” who became an undercover informant for shady FBI agents (Jennifer Jason Leigh and Rory Cochrane) in the 1980’s and was subsequently arrested for drug trafficking and sentenced to life in prison. Story fails to grab as a whole in part because Merritt’s character (and performance) is so one-note and aloof and both “Blow” and “Snitch” (among others) covered this territory already with a lot more fervor. Redeemed in part by authentically gritty Detroit surroundings and usual strong performance by Matthew McConaughey as his feisty but loving dad.
