Moonlighting (1985)

Maddie is a former model left broke by a swindle; David is the motormouth who talks her into becoming his partner in a detective agency. Moonlighting is the most romantic and talkative pick here, with rapid overlapping dialogue that plays like a screwball comedy wrapped around a case. The mysteries are often an excuse for the sparring, which is the point. It gets uneven once the will-they-won't-they question is settled, so treat the early seasons as the main event.
