“Interference” (** out of four) was a muddled psychodrama about a retiring world-weary detective (Bruce Thomas) who tries to discover the identity of a charred woman who is found in front of the boat of the District Attorney (Cayleb Long) who is pursuing a child serial killer. Half-baked and half-hearted ideas and characterizations borrowed from dozens of other cop and lawyer dramas but is given a marginal boost by Thomas who adds some spice and style. Inauspicious directing debut for noted sound effects editor Linda Di Franco.
