“Bridgerton” on NBC’s new dating show “The Courtship,” which premieres Sunday, March 6 at 8 pm. The show follows Nicole Rémy, a Seattle-based engineer and former Seattle Seahawks NFL dancer, and 16 suitors who go all-out with old-fashioned flourishes to charm her.Unlike regular dating shows, it’s set against the backdrop of a Jane Austen-like setting: They’re in Castle Howard in the rolling hills of England.
