“Mommy’s Secret” (** out of four) was a tepid crime drama about a teenage girl (Stephi Chin-Salvo) who suddenly realizes that her sincere and dedicated mom (Charisma Carpenter) is behind the recent rash of bank robberies in their town and is working for the main local crime boss! Potentially juicy story for a teenage melodrama, a criminal underworld thriller, a police procedural story, or the double life of a seemingly perfect suburban mom is too mild and never takes off and thus never succeeds at any of them. You can only imagine what a director like Christopher Nolan or Ron Howard might have done with material like this but as such- it never catches fire.
