“Being Charlie” (** out of four) was an earnest but superficial melodrama about a high-school drug abuser (Nick Robinson) sent to rehab by his gubernatorial-candidate father (Cary Elwes) but struggles to stay clean and get his life together as he goes from rehab to homelessness to jail. Unusual film from director Rob Reiner is written by his son Nick who struggled with drug addiction but despite a solid performance from Robinson, the result feels like a t.v. movie. The tacked-on happy ending rings especially false and for a movie called “Being Charlie”, the movie tells you little of who Charlie is. Common gives another searing performance as one of Charlie’s counselors.
