“Murder In Law” (** out of four) was a by-the-numbers and predictable “Mother-In-Law from Hell” melodrama about a young couple (Mark Collier and Kristen Dalton) whose lives are manipulated and their relationship soon torn apart by his evil mother (Barbara Williams). Full of predictable plot turns and plot contrivances although decent performances make this more bearable than most of its kind. Final showdown and plot twist is particularly weak. Why are the main characters in these thrillers always so naive and so dumb?
