“The Postcard Killings” (** out of four) was a wearily familiar adaptation of James Patterson’s novel about a hard-boiled NYC detective (Jeffrey Dean Morgan) and his estranged wife (Famke Janssen) who go to London to investigate the death of their daughter who was murdered on her honeymoon but find there may be a lot more duplicity and deception at play than either realize. Standard-issue Patterson story of murder and mayhem and cops and vengeance but it’s muddled and inert. Morgan is solid as usual and holds your interest for at least a little while but even he has played this role all-too-many times before. Elegant cinematography by Salvatore Tortino is another definite plus.
