This really is something to leave playing in the background because paying attention to it is insufferable. Good premise but it's dragged out with a really unlikeable protagonist (in fact, her niece is the only likeable character in the show by episode 3), and very awkward, clunky dialogue. The action scenes would be laughable on daytime TV in the 90s. Feels more like watching a soapie trying its hand at a murder mystery thriller than a high budget limited series.
Save your time and go watch The Bodyguard or The Diplomat instead.
