AVClub: “Retention,” the third episode of Starz’s new series The Girlfriend Experience, opens on Christine sitting alone in the expanse of a building. Then the camera tracks Jacqueline all the way from the front door to where Christine is standing, moving from a wide frame to something tighter. It’s an indicative opening shot because it visually sets up the themes of the episode, and the themes of the series in general, while also bringing Christine and Jacqueline face to face. It’s a sign of things to come. Christine spends much of “Retention” moving from large, overwhelming spaces to more cramped and intimate ones, and a confrontation between her and her employer is soon to come.
