“Secrets Of A Gold Digger Killer” (** out of four) was a bland suspense thriller about the title middle-aged woman (Julie Benz) who seduces a multimillionaire (Eli Gabay) and charms and insinuates herself into his family (Georgia Bradner and Roan Curtis) and attempts to murder him for his money. By-the-numbers story is cranked out without much suspense or surprises or (yes) secrets. Benz is strong as usual but is unable to enrich this tired material. Based on Suzy Spencer’s best-selling novel.
