“Stealing Cars” (** out of four) was a well-meaning but limited story of a rebellious teen (Emory Cohen) who gets arrested for stealing cars and placed in the juvenile court system and a detention center where the tough administrator (John Leguizamo) takes an active interest in him. Interesting story about the difficulties that youth and their social workers face is also dour and sluggish. Since the boy is never really likeable, it’s tough to get involved in him or his plight. Director Bradley Kaplan even has him watching “A Bronx Tale” in a few scenes, a reminder of the fire and conviction missing from his own movie
