“Catfish Murder” (** out of four) was a tame suspense melodrama about a single mom (Gina Holden) whose life is turned upside down when her young son (Quinten James) is arrested and accused of murdering a girl (Zoe Christie) that he met online and she is unsure of whether to immediately support him or to uncover whether or not he actually did it. Beautifully shot by Robert Rindeau and has an intriguing initial framework but descends more into the routine by the time of its predictable conclusion. Inauspicious English directorial debut of noted Kurdish director Soran Mardookhi.
